Room temperature ferromagnetism of a double-layer Dy1-xNix/Ni structure: in situ magneto-optical measurements

摘要

The double-layer Dy1-xNix/Ni structures have been studied in situ an ultrahigh-vacuum chamber by the original technique using the surface meridional Kerr effect directly in the course of deposition. It has been shown that a layer Dy1-xNix alloy is ferromagnetically ordered at room temperature.
