Abstract
The absorption of a magnetoelastic wave and the nonlinear resonance in teraction of counterpropagating magnetoelastic waves in a manganese-zi nc spinel single crystal have been investigated near the conjectured s pin-reorientational transition. The convolution signal vanishes near T -tr = 291 K; this is explained by the relaxational dynamics of the mag netic mode near the transition. The increase in the strength of the fi eld corresponding to the maximum of the convolution with decreasing te mperature is explained by a change in the demagnetizing field, (C) 199 7 American Institute of Physics.
