a Crystal structure of YIG. The blue, green, purple, and red spheres represent the Tet.-Fe3+, Oct.-Fe3+, Dod.-Y3+ and O2- ions, respectively. b Representative θ−2θ XRD pattern for a YIG (180 nm)/GGG film. c AFM images of the processed GGG substrate and a representative YIG (180 nm)/GGG heterostructure. d Normalized hysteresis loops measured with the magnetic field along the in-plane and out-of-plane at 300 K, respectively. Ms is the saturation magnetization.
