摘要：

The magnetic behavior of the R2CuGe6 ternaries (R = Gd, Tb, Dy and Er) was investigated in the temperature interval 1.72-300 K and in magnetic fields up to 5 T. All the compounds order antiferomagnetically with Neel temperatures of 20.6, 33.1, 22.0 and 5.6 K for R = Gd, Th, Dy and Er, respectively. Above the respective T-N the reciprocal magnetic susceptibility obeys the Curie-Weiss law with the paramagnetic Curie temperature being negative for R = Gd, Th and Dy and positive for R = Er.
