Geometric confinement (GC) of skyrmions in nanodomains plays a crucial role in skyrmion stabilization. This confinement effect decreases the magnetic field necessary for skyrmion formation and is closely related to the applied mechanical stresses. However, the mechanism of GC is unclear and remains controversial. Here, we numerically study the comb...

... contrast, in the free boundary model, n ij is not constant and depends on the position of bond ij. Figure 4(b) shows that n ij = 1 (n ij = 2) on (inside) the boundary. This result implies that S DM in the free boundary model is given by the second expression in Eq. (2) indicated by ( Fig. 3(b)). ...

... Its spontaneous magnetic properties are caused by the intrinsic strong spin-orbit coupling (SOC) derived from the 3delectron exchange interaction of V atoms. broken inversion symmetry necessary for the formation of DMI and skyrmions [5,6], several researches have adopted several ways to break the inversion symmetry in 2D systems, such as the electric field [17,18], Moiré rotation [19], doping, strain [20][21][22][23] and heterostructure [24]. Motivated by this approach, we studied a skyrmion crystal in H-VTe 2 monolayer by applying on the one hand external in-plane biaxial strain which has the effect of breaking the inversion symmetry and on the other hand by exploiting the competition that exists between the nearest-neighbor (NN) ferromagnetic interaction J, the magnetocrystalline anisotropy, the DMI interaction and this under the application of an external magnetic field B. The paper is organized as follows: Section 2 is dedicated to the description of our computational details and methods. ...
