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. |
