摘要：

The specific heat of the colossal magnetoresistance material Nd0.67Sr0.33MnO3 is reported for 0.35 less than or equal to T less than or equal to 280 K, H=0 and 1 less than or equal to T less than or equal to 120 K, H=9 T. The results include a Schottky-like specific-heat anomaly for the Nd ordering, an "attenuation" of the Mn ordering anomaly, and a T-dependent "linear term," gamma(T)T. This unusual combination of features is interpreted as arising from an interaction between the Nd and Mn spin systems. The expected magnetic entropy is recovered only if a contribution from the gamma(T)T term is included. [S0163-1829(99)03501-8].
