Abstract

The ternary intermetallic compound Pr117Co56.7Ge112 adopts the cubic Tb117Fe52Ge112-type related structure with the lattice parameter a = 29.330(3) angstrom. The compound exhibits one prominent magnetic transition at similar to 10 K and two additional weak magnetic anomalies are observed at similar to 26 K and similar to 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 Pr117Co56.7Ge112 obeys the Curie-Weiss law with a positive value of the paramagnetic Curie temperature (theta(P) = 24 K), indicating that ferromagnetic interactions are dominant. The effective magnetic moment is 3.49 mu(B)/Pr, which is close to the theoretical effective paramagnetic moment of 3.58 mu(B) for the Pr3+ ion. (C) 2013 American Institute of Physics.
