Spin valve devices, the resistive state of which is controlled by switching the magnetization of a free ferromagnetic layer with respect to a pinned ferromagnetic layer, rely on the scattering of electrons within the active medium to work. Here we demonstrate spin-valve-like effect in the Ni-Mn-In thin films, which consists of a ferromagnetic phase...

... have also performed MH measurements at 300 K for θ = 0, 45, and 90 • as shown in Fig. 3(c) (diamagnetic contributions from the quartz sample holder and substrate were subtracted from all the data). The curves show that the easy axis lies along the in-plane direction. The spontaneous magnetization at zero internal magnetic field is lowest for θ = 45 • . Also the curve at 45 • shows higher slope above the saturation magnetization, suggesting that the AFM matrix in the sample is possibly aligned along 45 • . Previous neutron-diffraction studies show that Mn moments in Ni-Mn are ordered antiferromagnetically either along [100] or [110] directions in the ab plane [24][25][26]. In the present case, it appears that the presence of In favors the AFM alignment along [100] (discussed in the following section). The [110] out-of-plane texture of the film thus means that the AFM matrix is at 45 • as shown in Fig. 3(d). Since there is no in-plane texturing, the AFM matrix is randomly distributed along the surface of a cone with 45 • angle. The magnetization measurement at 10 K after cooling under 5-T field does not show any exchange bias effect, indicating that the magnetic clusters in the film are of the order of a few nanometers as reported previously ...

Electric field control of magnetism through nanoionics has attracted tremendous attention owing to its high efficiency and low power consumption. In solid-state dielectrics, an electric field drives the redistribution of ions to create one-dimensional magnetic conductive nanostructures, enabling the realization of intriguing magnetoresistance (MR) effects. Here, we explored the electric-controlled nickel and oxygen ion migration in Pt/HfO 2-x /NiO y /Ni heterojunctions for MR modulation. By adjusting the voltage polarity and amplitude, the magnetic conductive filaments with mixed nickel and oxygen vacancy are constructed. This results in the reduction of device resistance by ~10 ³ folds, and lead to an intriguing partial asymmetric MR effect. We show that the difference of the device resistance under positive and negative saturation magnetic field exhibits good linear dependence on the magnetic field angle, which can be used for magnetic field direction detection. Our study suggests the potential of electrically controlled ion migration in creating novel magnetic nanostructures for sensor applications.
... Such a dependence at low temperatures rules out the single magnon scattering, an indication of the half-metallic nature of the alloy [3]. a crossover behavior (from negative to positive) starting from 50 K, which continues till 300 K. These features of MR clearly reflect the spin-valve-like behavior [12], which remains intact in the T range of 50-300 K and even under a field of 70 kOe [38]. One should note that the double hysteresis loop also points towards the spin-valve-like feature in this alloy. ...
We report a combined theoretical and experimental study of a novel quaternary Heusler system, CoFeVSb, from the viewpoint of room-temperature spintronics and thermoelectric applications. CoFeVSb crystallizes in a cubic structure with a small DO3-type disorder. The presence of the disorder is confirmed by room-temperature synchrotron x-ray diffraction and extended x-ray absorption fine structure measurements. Magnetization data reveal a high ordering temperature (∼850K) with a saturation magnetization of 2.2 μB/f.u. Resistivity measurements indicate a half-metallic or semimetallic nature. A double hysteresis loop along with asymmetry in the magnetoresistance data reveals a room-temperature spin valve feature, which remains stable even at 300 K. Hall measurements show anomalous behavior with a significant contribution from the intrinsic Berry phase. This alloy also has a large room-temperature power factor (∼0.62 mWm−1K−2) and ultralow simulated lattice thermal conductivity (∼0.4 Wm−1K−1), making it a promising candidate for thermoelectric application. Ab initio calculations suggest weak spin-polarized semimetallic behavior and reduced magnetization (in agreement with the experiment) in the presence of DO3 disorder. We have also found an energetically competing ferromagnetic (FM)/antiferromagnetic interface structure within an otherwise FM matrix, one of the prerequisites for spin valve behavior. The coexistence of so many promising features in a single system is rare, and hence CoFeVSb gives a fertile platform to explore numerous applications in the future.
... The main magnetic phenomenon specific to these F/AF systems is the unidirectional anisotropy exhibited in different applications, either by the specific exchange bias field (positive or negative), or by the increased coercive fields of the F layer interfacially-coupled to the AF layer, as compared to a simple free F layer [14,15]. Among the available nanoarchitectures today, the two-dimensional (2D) F/AF bilayer systems are mostly used due to their simple preparation protocols and because they are excellent candidates for spin-valve applications [16]. They have been also mostly studied with respect to the dependence of the unidirectional anisotropy parameters on the magnetic and geometric characteristics of the interfaced F and AF layers [17][18][19][20]. ...
We report the facile and low-cost preparation as well as detailed characterization of dense arrays of passivated ferromagnetic nickel (Ni) nanotubes (NTs) vertically-supported onto solid Au-coated Si substrates. The proposed fabrication method relies on electrochemical synthesis within the nanopores of a supported anodic aluminum oxide (AAO) template and allows for fine tuning of the NTs ferromagnetic walls just by changing the cathodic reduction potential during the nanostructures’ electrochemical growth. Subsequently, the experimental platform allowed further passivation of the Ni NTs with the formation of ultra-thin antiferromagnetic layers of nickel oxide (NiO). Using adequately adapted magnetic measurements, we afterwards demonstrated that the thickness of the NT walls and of the thin antiferromagneticNiO layer, strongly influences the magnetic behavior of the dense array of exchange-coupled Ni/NiO NTs. The specific magnetic properties of these hybrid ferromagnetic/antiferromagnetic nanosystems were then correlated with the morpho-structural and geometrical parameters of the NTs, as well as ultimately strengthened by additionally-implemented micromagnetic simulations. The effect of the unidirectional anisotropy strongly amplified by the cylindrical geometry of the ferromagnetic/antiferromagnetic interfaces has been investigated with the magnetic field applied both parallel and perpendicular to the NTs axis.
Nanoionic technologies are identified as a promising approach to modulating the physical properties of solid‐state dielectrics, which have resulted in various emergent nanodevices, such as nanoionic resistive switching devices and magnetoionic devices for memory and computing applications. Previous studies are limited to single‐type ion manipulation, and the investigation of multiple‐type ion modulation on the coupled magnetoelectric effects, for developing information devices with multiple integrated functionalities, remains elusive. Here, a dual‐ion solid‐state magnetoelectric heterojunction based on Pt/HfO2−x/NiOy/Ni with reconfigurable magnetoresistance (MR) characteristics is reported for in‐memory encryption. It is shown that the oxygen anions and nickel cations can be selectively driven by voltages with controlled polarity and intensity, which concurrently change the overall electrical resistance and the interfacial magnetic coupling, thus significantly modulate the MR symmetry. Based on this device, a magnetoelectric memory prototype array with in‐memory encryption functionality is designed for the secure storage of image and digit information. Along with the advantages including simple structure, multistate encryption, good reversibility, and nonvolatile modulation capability, this proof‐of‐concept device opens new avenues toward next‐generation compact electronics with integrated information functionalities.
