... 4 Also, antiferromagnets demonstrate resonant frequencies up to terahertz, which opens up the possibility of developing high-speed magnetic bias-free signal processing devices. [5][6][7] These advantages make antiferromagnets good candidates for developing microwave devices for potential applications in magnetic memory, 8 tunable detectors, [9][10][11] and oscillators, [12][13][14][15] waveguides, 16 etc. ...
... 20,21 In particular, the so-called strain-or stress-mediated magnetoelectric coupling is of high interest, especially for magnetic memory applications. 8,22 The research works into various effects caused by magnetoelastic interaction in antiferromagnets are conducted for a long time and are still relevant. 23 In contrast to previous works, [23][24][25] this article discusses the influence of uniaxial pressure on the frequencies of ferro-and antiferromagnetic resonance. ...
In this work, we present the results of investigations performed on hematite (α-Fe2O3), which is an antiferromagnet with weak ferromagnetism. Through the use of Brillouin light scattering spectroscopy, we studied experimentally the excitation of quasi-ferro- and antiferromagnetic modes in the bulk hematite. We investigated the influence of relative mechanical strains, ϵyy, on the frequencies of quasi-ferro- and antiferromagnetic modes. Also, we considered the angular dependence of the frequency of the quasi-ferromagnetic mode on the external magnetic field. Our results indicate that hematite is a suitable material for strain-controlled magnonic devices.
