“…In magnetically ordered crystals, the effect of coupling (between magnetic and elastic waves) has opened up many possibilities for the creation of controlled structures, therefore, research in this field is actual [14,15]. In particular, much attention was paid to study the properties of surface magnetoelastic waves in two-layer and multilayer films containing layers with different magnetic parameters.…”

In this work we present a model explaining the properties of magnetoelastic waves propagation in the heterostructure containing an antiferromagnetic layer on a non-magnetic elastic substate. Horizontally polarized shear surface waves (SH-waves) propagating in thin film are Love waves. The dispersion characteristic of magnetoelastic waves in such structure was obtained, and the effect of variation of the thickness of the antiferromagnetic layer and the external magnetic field on the frequency of the magnetoelastic resonance was also studied. It was found that an increase in the magnetic field magnitude leads to the increase in the magnetoelastic resonance frequency, and, on the contrary, with an increase in the thickness of the AFM layer the magnitude of the magnetoelastic resonance frequency decreases. The obtained results can be used to develop devices for generating and processing signals in the GHz and THz frequency ranges.

“…Поскольку АФМ-материалы имеют малый суммарный вектор намагниченности, это позволяет прикладывать магнитные поля меньшего порядка для генерации спиновых волн. Такие свойства делают АФМ хорошими кандидатами для разработки микроволновых устройств и потенциальных приложений для магнитной памяти [11], генераторов [12][13][14], волноводов [15] и др., поэтому исследования в этой области актуальны [16][17][18].…”

The results obtained can be used to create devices for generating and processing signals in the gigahertz and terahertz frequency ranges.

This paper presents a model that explains the influence of external pressure on the resonant frequency of a bulk crystal a–Fe2O3 in an external magnetic field. The dynamics of vectors l and m before and after the Morin temperature TM are considered. The dependences of the resonant frequency on pressure and external magnetic field for the cases H║(HA ║ z) and H┴(HA ║ z) are obtained, and the dependences of the magnetic field on pressure are obtained for the lower and upper modes. It was found that when external pressure is applied to the structure, the natural frequency of vibrations of the magnetic sublattices of the antiferromagnet increases significantly. The results obtained can be used in the development of devices for generating and processing signals in the gigahertz and terahertz frequency ranges.
