Abstract

Polycrystalline Fe/Au superlattices were prepared by monatomic layer control on quartz glass substrates with MgO underlayers having a (001) texture, and their structural and magnetic properties have been compared with those for monocrystalline samples grown on MgO(001) single-crystal substrates. X-ray analysis have shown that the interface roughness and/or the disorder of superlattice structure in polycrystalline samples are larger than those in monocrystalline samples. It has been found that the perpendicular magnetic anisotropy is very sensitive to the interface morphology, while the magnitude of the Fe moment and the magnetooptical Kerr spectra are not seriously influenced by the interface morphology.
