Abstract
The temperature and magnetic field dependences of transvers sound velocity for series of rare-earth compounds Tb0.27Dy0.73(Fe1-xMnx)1.9 (0<x<0.2) are studied experimentally. The maximum value of [MATH] G-effect has been obtained for concentration x=0.05. Double change of sign of nonlinear frequency shift for magnetoelastic mode in DC magnetic field rate 0<H<15 kOe was observed. The characteristic values of magnetic field strength for the change of sign are in agreement with mechanism of intermode nonlinear interaction.
