Thermodynamical study on the heavy-fermion superconductor PrOs4Sb12: Evidence for field-induced phase transition

We report measurements of low-temperature specific heat on the 4 f 2 -based heavy-fermion superconductor PrOs 4 Sb 12 . In magnetic fields above 4.5 T in the normal state, distinct anomalies are found which demonstrate the existence of a field-induced ordered phase (FIOP). The Pr nuclear specific heat indicates an enhancement of the 4 f magnetic moment in the FIOP. Utilizing a Maxwell relation, we conclude that anomalous entropy, which is expected for a single-site quadrupole Kondo model, is not concealed below 0.16 K in zero field. We also discuss two possible interpretations of the Schottky-like anomaly at ∼3 K, i.e., a crystalline-field excitation or a hybridization gap formation.
