N2 - L10-FeNi, showing uniaxial magnetic anisotropy (Ku) of 1.3×107 erg/cm3 in a bulk sample[1], is promising as a 'rare metal-free' high Ku material. It is known that iron meteorites contain the L10-FeNi phase, what is called 'tetrataenite', which reveals unique magnetic properties different from usual Fe-Ni alloys[2]. However, the artificial fabrication of L10-FeNi is difficult because the order-disorder transformation temperature is low (∼320C), and below this temperature the atomic diffusion is extremely slow. In this study, we have tried to fabricate L10-FeNi thin films with high Ku by two methods: molecular beam epitaxy (MBE) and sputtering.
