Abstract In the present study we have presented the magnetic and magnetocaloric properties of ferromagnetic (La0.67Sr0.33MnO3)-charge ordered (Pr0.67Ca0.33MnO3) core-shell nanostructures. We have also compared the magnetocaloric properties of Pr0.67Ca0.33MnO3 (PCMO) nanoparticles. Our study indicates that in case of the core-shell nanostructures, the magnetocaloric properties markedly modifies compared to its parent compound PCMO, additionally the low field magnetocaloric effect enhanced. More specifically, the large value of magnetocaloric entropy change (− Δ S(T)) was observed in wider temperature range in core-shell nanostructure which may be important from application point of view.
