Complex magnetic behavior in Pr2Cu0.8Ge3

The Pr-based ternary germanide Pr2Cu0.8Ge3 has been characterized by means of magnetization, heat capacity and electrical resistivity measurements. The compound has been found to order magnetically at T1 = 13.4 K and then undergo two subsequent magnetic phase transitions at T2 = 11.8 K and T3 = 11.2 K. The magnetization and specific heat data indicate that the electronic ground state in Pr2Cu0.8Ge3 has a ferromagnetic-like character.
