The Nd 0.6 Sr 0.4 MnO 3  sample has been synthesized by the solid-state reaction. In this research paper, structural, morphological, magnetic and magnetocaloric properties are reported. The refinement by Fullprof has revealed the coexistence of both Pnma orthorhombic and R-3c rhombohedral phases. The obtained magnetic results show a paramagnetic–ferromagnetic transition at  T  C  = 245 K. The magnetocaloric effect was estimated from the magnetic isotherms. We can estimate that the magnetic entropy change (Δ S ) values by the Hamad theory are very close to those obtained using the classical Maxwell relation. Under an applied field 5 T, the maximum of the magnetic entropy change (Δ S ) max and the relative cooling power is found to be 3.68 J/kg K and 216.03 J/kg, respectively. The obtained values are compared with those of some other reported manganite and show that our compound could be a promising candidate for magnetic refrigeration. Finally, the construction of the universal curve of the magnetic entropy change confirmed the studied manganite undergoes a second-order magnetic phase transition.
