摘要：
The magnetic properties of a single-crystalline sample Ce2Sc3Ge4 have been investigated, for the first time. On the basis of the magnetization, magnetic susceptibility, electrical resistivity and specific heat measurements, we suggest that Ce2Sc3Ge4 is an antiferromagnetic Kondo compound with T-N = 5.0 K. The saturated magnetic moment for the Ce atom is estimated to be 1.1 mu(B) at T = 1.5 K by the magnetization measurements. Electronic specific heat coefficient gamma is estimated to be 49.5 mJ/molK(2), indicating that the system is described as a medium-heavy fermion compound.
