DOI: 10.1063/1.4982244
Abstract: We have investigated the magnetocaloric effect (MCE) of Ba1-xSrxFe4+O3 (x≤0.2), a series of cubic perovskites showing a field-induced transition from helical antiferromagnetism to ferromagnetism. The maximum magnetic entropy change (-ΔSmax) at 50 kOe varies from… read more here.
