Zusammenfassung: 
The XPS electronic structure was measured for YMn2, GdMn2, ErMn2, YMn4Al8 and GdMn4Al8 single crystals and pure Mn. Exchange splitting of Mn 3d and 3s states was found for the compounds with magnetic manganese. The electrical resistivity of the GdMn2 single crystal shows an antiferromagnetic transition at 108 K and the second transition at 32 K. The lattice parameter against temperature of GdMn2 exhibits a large spontaneous magnetostriction at T-N. The anisotropic character of the GdMn2 magnetization was found. The results were discussed using the Yamada and Shimizu model.
