Abstract

The ternary intermetallic compound Pr117Co56.7 Ge 112 adopts the cubic Tb117Fe52 Ge 112-type related structure with the lattice parameter a = 29.330(3) Å. The compound exhibits one prominent magnetic transition at ∼10 K and two additional weak magnetic anomalies are observed at ∼26 K and ∼46 K in a 1 kOe applied field. At a higher field of 10 kOe, only one broad ferromagnetic-like transition remains at 12 K. The inverse magnetic susceptibility of Pr117Co56.7 Ge 112 obeys the Curie-Weiss law with a positive value of the paramagnetic Curie temperature (θP = 24 K), indicating that ferromagnetic interactions are dominant. The effective magnetic moment is 3.49 μ B/Pr, which is close to the theoretical effective paramagnetic moment of 3.58 μ B for the Pr3+ ion.
