Hybrid interface composed of organic molecules and an inorganic magnetic substrate attracts attention due to its controllable interfacial spin state by the molecular adsorption structure. In this work, we fabricate H2Pc/ Fe2N organic-inorganic hybrid interface and investigate intrinsic interfacial electronic and magnetic properties. We reveal from XAS/XMCD measurements that the magnetic coupling at H2Pc/ Fe2N organic-inorganic hybrid interface enhances the perpendicular magnetic anisotropy of Fe2N, but disappears with increasing H2Pc coverage. Accordingly, we investigate details of the magnetic coupling at H2Pc/ Fe2N organic-inorganic hybrid interface by STM/STS and confirm the importance of N atoms in H2Pc on the magnetic coupling with Fe2N.
