摘要: We have shown that, in the presence of a strong ac magnetic field, parametric interaction two weak acoustic waves occurs crystal molecular magnets. Any molecule is subject to dc field perpendicular its easy anisotropy axis. The parallel this frequencies and are close transition frequency fundamental doublet. propagate opposite directions. derived equations for amplitudes coupled waves. Due interaction, one wave input into sample excites second wave.
