摘要：

The specific heat (C) of the colossal magnetoresistance material Nd0.67Sr0.33MnO3 was measured for 0.35 < T < 280 K and 0 less than or equal to H less than or equal to 9 T. Estimates were made of contributions to C from the hyperfine interactions, the lattice, Nd3+ magnetic ordering, ferromagnetic ordering of the Mn ions near T-c approximate to 205 K, and a low-T gamma T term. The entropy associated with the last three terms is essentially equal to that expected for the ordering of the Nd and Mn moments. (C) 1998 Elsevier Science B.V. All rights reserved.
