Structural and Magnetic Properties of Pt/Fe(lll) Multilayered Films Containing Monolayer-thick Fe Layers
Year: 2008
Type: article
Abstract: The [111] oriented Pt/Fe multilayered films were fabricated by electron beam evaporation in an ultra-high vacuum of 10-8 Pa.Keeping the thickness of Fe at 0.2 nm corresponding to one atomic monolayer (ML), several samples with the different Pt layer thickness (np 1 ) from I to 8 ML were deposited on the Si-wafer covered with 20 nm thick Au(lll) buffer layer.XRD patterns of the samples with np 1 ::: 2 showed well-resolved superlattice peaks.Superlattie periods from XRD and atomic compositions evaluated by RBS spectra almost agree with the designed ones.All the films are ferromagnetic even at room temperature.The magnetization decreases with the increase of np 1 at 300 K, suggesting the two dimensional effect for high np 1 • For the sample with np 1 =8, the perpendicular magnetic anisotropy was observed at 5 K. Details of the XRD intensity analysis indicate the alloy layer formation.
