Piezoelectric changes of anisotropy and magnetization in ferrite-garnet film

Abstract

The results of the effect of mechanical strain on magnetic anisotropy, the direction of magnetization vector and domain structure of ferrite-garnet film, rigidly connected with the zirconium-titanium lead (PZT) piezoceramic plate are presented. Since such a sandwich structure could be remagnetized both by magnetic field and electric voltage it could be used as the electro-magnetooptical modulator of light or spin switching cell in spintronics.
