Investigation of the magnetocaloric effect and phase transition in a newly discovered perovskite oxide La0.7Ba0.25Nd0.05Mn1-xZnxO3 for x = 0.03 and 0.05 [PDF]

EPJ Web of Conferences
In this study, we examine the magnetocaloric behavior of the newly discovered perovskite oxide La0.7Ba0.25Nd0.05Mn1-xZnxO3 (x = 0.03 and 0.05). We focus on key magnetocaloric parameters, such as magnetic entropy change, heat capacity change, full-width ...
