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.
