Structural, magnetic and magnetocaloric properties of La0.65Sr0.35V0.1Mn0.9O3 perovskite

Abstract A new complex magnetic material La 0.65 Sr 0.35 V 0.1 Mn 0.9 O 3 , 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 ∼ 1.56 J/kg K and the relative cooling power value of 67 J/kg at magnetic field variation of 1 T.
