摘要：

Neutron powder diffraction experiments and magnetization measurements have been carried out on the intermetallic compound Ce4Ge3 (Cubic, Th3P4-type). The neutron diffraction data obtained in zero field at 2 K, reveal commensurate antiferromagnetic ordering with magnetic moments of Ce directed along (0 0 1) axis (M-Ce = 1.55(4) mu(B)) whereas the magnetization data depict two magnetic transitions at similar to 12 K and at similar to 6 K, respectively. Isothermal magnetization data obtained at 2 K present complex metamagnetic transition with two plateaus corresponding to magnetic moment values of similar to 0.35 mu(B)/Ce3+ in 2T and similar to 0.94 mu(B)/Ce3+ in 9T field.
