BiFeO3/L10 CoPt layered films are prepared by sputtering on MgO (0 0 1) substrates. Both X-ray diffraction and transmission electron microscopy confirm the (0 0 1)-epitaxial growth. Magnetic field-mediated two magnetic states phenomenon has been observed in this layered films. Element mapping results indicate there exist Co-deficient CoPt layer (∼1.5 nm) and Co-containing BiFeO3 layer (∼2 nm) adjacent to the BiFeO3/CoPt interface. After applying in-plane or out-of-plane external magnetic field, moments in the above layers react differently, leading to two disparate magnetic states: coupling and decoupling states.
