Abstract

La0.8Sr0.2Mn1−xCoxO3 (x = 0, 0.2) polycrystalline samples were prepared by solid-state reaction, and their structural, Griffiths phase, magnetic entropy change, critical behavior, and electrical transport properties were systematically investigated. The results show that all polycrystalline samples are rhombohedral symmetry structures; the Griffiths phase exists above the low-temperature magnetic transition temperature (TC2) of the two samples; the magnetic field is applied to the La0.8Sr0.2Mn1−xCoxO3 (x = 0, 0.2) samples. The maximum magnetic entropy change ΔSmax for 7 T is − 2.28 and − 2.36 J/(kg K), respectively. The doping of Co makes ΔSmax increase, and an obvious negative entropy change occurs at low temperature and low field; the critical behavior of La0.8Sr0.2MnO3 (LSMO) fits best with the mean field model, and the critical behavior of the sample after doping with the 3D Heisenberg model fits best; LSMO is a semiconductor material, and the metal insulator transition appears near the low-temperature magnetic transition temperature (TC2) when the Co element doping amount reaches 0.2. The conductivity of the two samples in the high-temperature region satisfies the small polaron model.
