Recent theoretical calculations predicted that a system composed exclusively of 3d transition metals without 4d/5d transition metals or rare earth metals can have strong perpendicular magnetocrystalline anisotropy (MCA) if Fe and Ni layers are arranged appropriately. They considered only Fe-terminated surfaces, noting that Fe/MgO(001) and CoFeB/MgO(001) show strong perpendicular MCA. In this paper, we investigate magnetism and MCA of Ni/Fe (001) Fe 원소를 중심으로 Mn, Co, Ni 원소와 결합한 3d 전이 금속만으로 구성된 박막의 자기이방성을 최근 이론 계산을 수
