Metamagnetic-like anomaly in CeCu 6

Abstract

The field dependences of specific heat C and magnetocaloric effect (MCE) Δ T/Δ B in CeCu 6 have been measured to investigate the thermodynamical aspects of the weak metamagnetic-like anomaly (MA). Around 1.7 T both properties exhibit anomalous behaviors, which have close similarities with those in CeRu 2Si 2. This fact suggests that the quasiparticle density of states in CeCu 6 has a faint peak structure near the Fermi level, which is superposed on the Kondo-resonance peak.
