摘要:
We report the magnetic properties of Ce2CuGe6 and Pr2CuGe6, both of which exhibit a ferrimagnetic order around 15K. Hysteretic curves with small residual magnetization, 7.8 x 10(-4) mu(B)/f.u. and 1.1 x 10(-2) mu(B)/f.u., are observed for Ce2CuGe6 and Pr2CuGe6, respectively. The peak of specific heat and the sharp decrease of electrical resistivity near their ordering temperature are consistent with observed magnetic orders.
