[HTML][HTML] Tuning the magnetic phase transition and the magnetocaloric properties of La0. 7Ca0. 3MnO3 compounds through Sm-doping
In this work, we point out that the width and the nature of the magnetic phase transition, TC
value, and as well as magnetocaloric effect in La 0.7-x Sm x Ca 0.3 MnO 3 compounds can
be easily modified through Sm-doped into La-site. With an increasing Sm concentration, a
systematic decrease in the magnetization, TC, and magnetic entropy change (ΔS m) are
observed. The Arrott-plot proveds that the samples with x= 0 and 0.1 undergoing a first-order
phase transition. Meanwhile, sample x= 0.2 undergoes a second-order phase transition …
