In the previous meeting, we reported observation of spin Hall magnetoresistance (SMR) in a rock-salt type LaO/EuO heteroepitaxial thin film with clean and sharp interface using EuO, a ferromagnetic insulator with Curie temperature of 69 K, as the bottom layer. This is the first report on SMR in oxide heterostructure. Here, we report the spin parameters of LaO derived from the LaO layer thickness dependence of SMR in LaO/EuO.
