Abstract:
This research reports the findings of large low-field magnetocaloric effect in polycrystalline Pr1−xPbxMnO3 (0.1⩽x⩽0.5) perovskites. It is found that, upon an applied field of 13.5kOe, the magnetic entropy change (ΔSM) reached values of 3.91, 3.68, and 3.34J∕kgK for x=0.1, 0.4, and 0.5 compositions, respectively. These values are larger than that of Gd (3.32J∕kgK) and were attained by a low applied magnetic field that can be generated by permanent magnets. These superior magnetocaloric features together with a relatively low material cost make the Pr1−xPbxMnO3 perovskites attractive candidate materials for magnetic refrigerators in a temperature range of 150–270K.
