Specific heat (C) studies with a wide range of temperatures (T = 80-300 K) on polycrystalline manganites Pr1-xCaxMnO3 (113-PCMO) with x = 0.3-0.4, La1-yCayMnO3 (113-LCMO) with y = 0.3 and 0.5, and La2-2zSr1+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.
