We present structural, chemical and magnetic properties of the van–der–Waals material FeBr2 on Au(111) with thicknesses from submonolayer to multilayer. We observe that the first layer on Au(111) shows a dominant superstructure. The chemical characterization by XPS and XAS shows that the material is growing in the same composition for different thicknesses. The magnetic characterization by XMCD reveals that the magnetic moment increases with increasing thickness.
