Influence of Strain on AFMR Modes of Trigonal Weakly Ferromagnetic Easy-Plane Antiferromagnets
摘要
AFMR modes for trigonal weakly ferromagnetic easy-plane antiferromagnets subjected to mechanical stress of arbitrary direction have been calculated by expressing magnetic, elastic and magnetoelastic energy densities and explicitly taking into account hexagonal magnetocrystalline anisotropy. This approach has been applied to parametrizing AFMR data for iron borate, a material promising for modern scientific and technical applications, such as synchrotron facilities, spintronics, etc.
