Reorientation of Magnetization in Single Crystalline Yttrium Iron Garnet Film under Mechanical Strain

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. It was established, that applied mechanical strain caused a 90°-reorientation of the magnetization vector from the initial perpendicular-to-plane into in-plane state. This strain acts similarly as applied magnetic field and when it applied simultaneously with the field, the piezovoltage necessary for reorientation is inversely proportional to magnetic field intensity. Such properties makes sandwich structures promising for use in spintronics and optoelectronics as a multicontrolled modulator of light.
