摘要:
Possible types of phase transitions as well as the spectra of coupled magnetoelastic waves are studied in an easy-plane ferromagnet with a rigidly fixed face. It is shown that the presence of such mechanical boundary conditions leads to a change in the type of phase transition. The dynamic properties of the system become most interesting at the point of absolute instability of the system rather than at the phase transition point. ©1998 American Institute of Physics.
