High magnetic anisotropy is one of the requirements for the permanent magnet material. L10-ordered FeNi, which exhibits large magnetocrystalline anisotropy, is a possible candidate for rare-earth-free permanent magnet material. Because of the difficulty in producing bulk amount of L10 FeNi, alternate monolayer stacking of Fe and Ni by molecular beam epitaxy was developed [1]. In order to enhance the degree of crystalline order of the L10 structure and the magnetocrystalline anisotropy, several kinds of buffer layer have been adopted so far [2,3]. Therefore the structural and magnetic depth profile of the multilayer stacking needs to be analyzed to optimize the fabrication procedures. In this study, we performed a polarized neutron reflectometry (PNR) experiment on multilayer samples including L10-ordered FeNi
