  In this paper, we report on the magnetocaloric properties of some selected
multiferroic oxides, namely HoMn2O5 and La2(Ni,Co)MnO6 compounds which exhibit
transition points from 10K up to almost room temperature. In order to avoid
grain boundary effects and structural inhomogeneity observed frequently in
polycrystalline samples, only single crystals were considered for this study.
