Abstract
The magnetic structures and the magnitudes of the ordered magnetic moments for the hexagonal ternary U2N2M-type compounds (where M is P, As, S, Se) have been determined by neutron diffraction. In U2N2S and U2N2Se the observed magnetic unit cells have the same size as the chemical ones while in U2N2P and U2N2As the magnetic unit cell is doubled along the c-axis. At 4K the magnetic moments on the uranium ion amount to 1.4, 1.7, 1.6 and 2.3 mu B for U2N2S, U2N2P, U2N2As and U2N2Se, respectively. In all of them the direction of the magnetic moment is along the c-axis.Keywords
