摘要

Specific heat (C) studies with a wide range of temperatures (T = 80-300 K) on polycrystalline manganites Pr_1-xCa_xMnO₃ (113-PCMO) with x = 0.3-0.4, La_1-yCa_yMnO₃ (113-LCMO) with y = 0.3 and 0.5, and La_2-2zSr_1+2zMn ₂O₇ (327-LSMO) with z = 0.3 and 0.5 are reported. Clear anomalies in C are identified which are associated with charge ordering (CO), antiferromagnetic (AFM) and ferromagnetic (FM) transitions. The anomalies in 113-PCMO and 113-LSMO are bigger than those of 327-LSMO. The possible explanations are discussed on the basis of dimensionality effects.
