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
