XMCD study of epitaxial 2D ferromagnets

The field of 2D ferromagnets is rapidly growing as in the last decades scientists have been learning how to master their synthesis with improved accuracy. Epitaxial methods allow precise control on the number of layers, favor the stabilization of different phases and allow magnetic coupling with specific substrates. All these variables make possible a variety of magnetic behaviors different from the bulk, whose mechanism needs to be understood. Here we want to study spectroscopically some few-layer thick epitaxial films recently obtained at Grenoble CEA in one of the SPINTEC groups, and exhibiting interesting magnetic properties, as already observed by SQUID. The materials which are the object of this in-house experiment ate 1) chromium ditelluride (CrTe2), 2) iron germanium ditelluride doped with Co (Fe(5-x)Ge(x)Te2) and 3) chromium diselenide (CrSe2).
