A series of multiferroic materials with the compositional formula RMn2O5 (where R=Tb, Dy andHo)were prepared by the solid state reaction technique. After characterising the samples structurally, a systematic investigation of specific heat, magnetization and dielectric studies has been undertaken, over a temperature range of 4–300 K. Based on these studies, it has been observed that all the samples exhibit multiple transitions below 45 K. A large magnetic anisotropy, primarily originating from spin-orbit coupling of R3+ moments was clearly observed in these materials. Finally, the magneto-caloric effect (MCE) computations were also carried out, mainly to examine the feasibility of using these materials as magnetic refrigerants. Suitable qualitative explanations for the various phenomena observed in this investigation are given.
