(a) Atomic force microscopy (AFM) image of 100 nm YIG film on GGG (111). (b) The size of the sample and the measurement method. Here, thermal gradient ΔT is along the z direction, the easy magnetization axis of the NiFe layer is along the +y direction, and the rotatable magnetic field is applied in the xy plane. (c) The in-plane hysteresis loop of 100 nm YIG. (d) The out-of-plane hysteresis loop of 100 nm YIG.
