Abstract

Magnetocaloric properties of nanostructured pristine and Bi-doped La0.7Sr0.3MnO3 samples, synthesised by high-energy planetaryballmilling,arepresentedhere.Theaimofthestudyistounderstandtheeffectofmillingtimeonmagneticentropychange, relative cooling power and changein specific heat. The magnetocaloric property, defined as the change in the magnetic entropy, has been determined by using aphenomenological model applied to the magnetic susceptibilityplots. Replacing 10% LabyBiin La0.7Sr0.3MnO3 significantlyaltersthechangeinmagneticentropy.Correlationbetweentheparticlesizeandmagneticentropyis observed in the present study. As the milling time increases from 0 h (bulk) to 48 h, the particle size reduces causing significant modifications in the magnetocaloric properties
