Abstrakt: In this paper, we show that, in the presence of two strong ac magnetic fields, a weak acoustic wave interacts with a crystal of molecular magnets. We obtain the analytical expression for absorption and group velocity in the linear case and discuss the effect of two coupling fields intensity on absorption and group velocity. Then, we find and analyze a series of generalized analytical solutions for nonlinear acoustic wave propagation in molecular magnets with arbitrary linear and nonlinear coefficients.
