摘要：

A new complex magnetic material La0.65Sr0.35V0.1Mn0.9O3, suitable for the magnetic refrigeration, has been investigated. X-ray diffraction result showed that this compound had rhombohedral structure. The substitution of manganese with V leads to a decrease in the Curie temperature, T-c from 378 K to 353 K. Using Arrott plots: it was found that the phase transition for this compound is of the second-order. The magnetocaloric study exposed a quite large value of the magnetic entropy change similar to 1.56 J/kg K and the relative cooling power value of 67 J/kg at magnetic field variation of 1 T.
