Magnetic Order of Co0.1Pt0.9 in Proximity of CoPt3
Published online by Cambridge University Press: 10 February 2011
Abstract
A polarized neutron reflectometry study of the magnetization density depth profile of a Co0.1Pt0.9-CoPt3 bilayer film found evidence for an induced moment in the Co0.1Pt0.9 overlayer in close proximity to the CoPt3 underlayer. If the moment of Co in these films is that of the bulk, then the μpt = 0.09(1)μB in the overlayer, and μpt = 0.04(1)μB, in the underlayer. In addition, ferromagnetic order of the Co0.1Pt0.9 overlayer was observed 8K above Tc for the material in the bulk.

4. The roll-over of the X-ray reflectivity profile below Q is caused when the cross-section of the beam is larger than the cross-section of the sample. The reflectivity of the sample is still unity for Q<Qc, and the roll-over can be accounted for with a simple geometrical factor.Google Scholar
