In this paper, the magnetocaloric effect of perovskite manganite Nd0.6La0.01Sr0.3MnO3 has been investigated. From the measurement of isothermal magnetization around the Curie temperature, we have calculated the maximum isothermal magnetic entropy change as 3.14 J/kg K for the 1.5 T magnetic field variation. Furthermore, a large relative cooling power of 45J/kg has been determined, which makes Nd0.6La0.1Sr0.3MnO3 attractive candidate materials for magnetic refrigeration.
