RHJ loops obtained at T= 90 K. Inserted schematic illustrations are the side view of schematic magnetization alignment in the SRO/STO heterostructure corresponding to the indicated points in processes 1, 2, and 3. The gray region represents the STO substrate. The red and blue regions denote magnetic domains with the upward and downward magnetization directions, respectively. These regions correspond to 8% of the 26 nm-thick SRO film near the SRO/STO interface, where the magnetization is likely switched in processes 2 and 3 at 90 K. The pink region is the mixed region of the upward and downward magnetization domains. The dark gray region represents the dead layer of the SRO film.
