摘要
Specific-heat data up to 12.5 T are presented for CeRu2Si2, Ce(Ru0.5Rh0.5)2Si2, and CeRu2Si1.8Ge0.2. The behaviors with field of the specific heats are compared, also with susceptibility data. The possibility that the maximum in C/T, or, at Hmetamagnetic=8 T in CeRu2Si2 corresponds to an increase in m* at the metamagnetic transition is discussed. Similar data for CeB6 are compared. © 1990 The American Physical Society.
