Waves Generation by Spiral Magnets at Phase Transitions

Abstract:

Article Preview

The possibility of electromagnetic and acoustic waves generation by magnets with spiral spin structure at phase transition to collinear state has been shown. Intensities and frequencies of generated waves have been calculated. It has been shown that intensities of both electromagnetic and acoustic waves strictly depend on the phase transition kinetics.
