Effects of rare earth ions substitution on the magnetocaloric and critical behavior of La0.6A0.2Sr0.2MnO3 (A=Pr, Nd, Ce) manganite
Review articleOpen access

Highlights•Magnetocaloric properties of La0.6A0.2Sr0.2MnO3 (A = Pr, Nd, Ce) samples have been studied.•Pr and Nd doped samples are single phase, but Ce doped samples have a CeO2 secondary phase.•Curie temperature, TC decreases with Pr and Nd doping, while Ce doping led to increase of TC.•MS of pure and Nd doped samples are higher than that of Pr and Ce doped samples.•The Arrott plots and universal curves indicate the samples undergo second order phase transition.
