摘要: Perpendicular magnetic anisotropy has been investigated for Fe(x ML)/Au(x ML) superlattices (ML: monatomic layer thickness) with x ranging from 1 to 4. The x-ray diffraction analyses indicate the formation of coherent layered structures both x=integers and nonintegers. However, perpendicular x=nonintegers shows different behavior that x=integers, consequently, it oscillates as a function period ML. Furthermore, out-of-plane lattice spacing also in same manner.
