초록

A theoretical consideration for entropy changes in a magnetic solid is given in a general manner and has been taken into account for such La$\sub$0.7/Ca$\sub$0.3-x/Ba$\sub$x/MnO$_3$(x = 0.12, 0.24, 0.3) compounds. The total entropy changes, in which the total entropy is decomposed into the magnetic, lattice, and electron entropies, are discussed in detail. (omitted)
