摘要
Novel ternary compounds RE(2)TGe(6) (RE=Y, La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb; T=Pd, Pt, Ag, Au) were synthesized by argon are melting followed by a heat treatment at 600 or 800 degrees C for 150 h. From X-ray powder analysis all compounds were found to be isotypic with structure type Ce,CuGe6. Magnetic susceptibilities were measured for RE(2)CuGe(6) (RE = Ce, Pr, Nd, Sm) and Ce(2)dGe(6). All compounds exhibit antiferromagnetic ordering below 20 K. The paramagnetic effective moments agree with the values for tripositive RE ion moments. The Sm containing sample reveals typical Van Vleck type paramagnetism above the Neel point.
