METHOD OF GENERATION, AMPLIFICATION AND MEASUREMENT OF HYPERSONIC WAVES IN MAGNETIC CRYSTALS

The mechanism of amplification, generation and measurement of parameters of acoustic and magnetic waves in a range of frequencies 1011-1012 Hz is considered at movement of domain wall in orthoferrites.

Keywords: acoustic waves, domain wall, weak ferromagnets, method of slowly varying amplitudes, magnetic waves, yttrium orthoferrite.
