Magnetic and magnetocaloric effect study of a polycrystalline Gd_0.5Sr_0.5−xCa_xMnO₃ compound

Abstract

The variation of the maximum value of magnetic entropy changes with the doping concentration x of Gd0.5Sr0.5−xCaxMnO3 (x = 0.0, 0.2, 0.3, 0.4 and 0.5) compounds.

Expansion of the multifunctionality in off-stoichiometric manganites using post-annealing and high pressure: physical and electrochemical studies

“…Rare-earth perovskite manganites have been extensively studied in the past few decades owing to their easy chemical production and structural diversity, as well as colossal magnetoresistance and high magnetocaloric effect (MCE) near the Curie temperature T C . [1][2][3][4] All these have significantly increased interest in them and promoted the search for ways of their potential practical applications in magnetic memory devices, batteries, fuel cells, transistors, spintronic and electronic devices, magnetic refrigerators, medicine for treating cancer, and drug delivery. [5][6][7][8] The recent development of new magnetic refrigeration technology based on the MCE has become an alternative green and environmentally friendly approach compared to the conventional gas compression technique.…”
