Abstract

Fractional numbers of atomic layers have been introduced intentionally into Fe/Au monatomic multilayers in order to investigate the effect of the deviation from monatomic layer thickness on the layered structure. We prepared [Fe(1 + δ ML)/Au(1 + δ ML)] multilayers with the fraction δ = 0, 0.25 and 0.5, where ML represents monatomic layer thickness. The superlattice (001) peak associated with the L1o ordered structure is observed in the X-ray diffraction profile for δ = 0. For δ = 0.25 and 0.5, on the other hand, the superlattice (001) peak is split into a couple of sharp peaks. The appearance of those two peaks indicates the formation of coherent layered structure with long-range periodicity, even for samples with fractional atomic layers.
