摘要：
Preliminary results of specific heat measurement in applied magnetic fields on the filled skutterudite CeOs4Sb12 are presented. Clear anomaly in the specific heat data suggests the existence of an intrinsic phase transition at 0.9 K, accompanied by a gap opening in moderately mass-enhanced quasiparticle bands. Unusual magnetic field effect on the transition temperature, which shifts toward higher temperatures with increasing field, is revealed.
