摘要：

The results are reviewed of the 15-year development of the concept of effective anharmonicity of the normal modes that describe the vibrations of a continuous medium having two or more mutually coupled subsystems. Magnetoelastic interaction near a spin reorientation phase transition leads to a giant acoustic nonlinearity and its magnetic field sensitivity in antiferromagnets such as alpha-Fe2O3, FeBO3, TmFeO3, etc.
