Fig. 5. Magnetic-field dependence of the YIG (2 μm) /TiO2 (0.2 μm) /PZT (400 μm) structure in a parallel (1) and perpendicular (2) configuration of the external magnetic field and the plane of the layer. Measurements were taken at 300 K. The insert is the same on a larger scale.

Fig. 6. FMR curves of the YIG (2 μm) /TiO2 (0.2 μm) /PZT (400 μm) structure samples in a resonant magnetic field parallel (a) and perpendicular (b) to the plane of the layer. Measurements were taken of four parts of the same sample. H is the resonance absorption line width.
