Abstract

Specific heat and magnetization measurements were performed on single crystalline PrPd_3S_4. A λ-type anomaly at T_M=1.56K in the specific heat shifts to higher temperatures by magnetic fields, begins to shift to lower temperatures above 2T, and disappears above 3.6T. The 4f ground state of Pr^<3+> was deduced to be a magnetic triplet. Below T_M, the magnetic susceptibility increases while no spontaneous magnetization appears. These results strongly reveal that PrPd_3S_4 shows a multipolar ordering at T_M. The most probable ordering state for PrPd_3S_4 is an antiferroquadrupolar (AFQ) ordering since the B-T phase diagrams are of the "re-entrant" type, which is typical for AFQ ordering compounds.
