Abstract: A magneto-optic thin film includes a substrate; a diffusion barrier layer disposed on the substrate, where the diffusion barrier layer includes a metal oxide; a buffer layer disposed on the diffusion barrier layer; and an optical isolation layer disposed on the buffer layer. The metal oxide in the diffusion barrier layer growing on the substrate is polycrystalline.
