摘要：

Polycrystalline samples of the solid solution U(Ni0.1Cu0.9)2Ge2 have been investigated by neutron diffraction and ac susceptibility. This material exhibits the tetragonal ThCr2Si2-type crystallographic structure. It orders ferromagnetically at T(C) = 115 +/- 5 K, undergoing another transition at T0 = 100 +/- 5 K to a ferrimagnetic phase with a wave vector k = (0,0,2/3) and with (+ + -) stacking of ferromagnetic planes of uranium magnetic moments [(1.9 +/- 0.2)mu(B) at 10 K] along the tetragonal axis. The magnetic properties of U(Ni0.1Cu0.9)2Ge2 are discussed in reference to the tentative magnetic phase diagram (temperature versus composition) of the U(Ni1-xCux)2Ge2 system.
