Abstract:We have investigated the structural, magnetic properties and magnetocaloric effect (MCE) in LaMnSbO 0.8 F 0.2 . The compound has the ZrCuSiAs-type structure with P4/nmm space group. For a field change of 0-5 T, the maximum entropy change (-DS M ) is calculated to be 0.074 J kg À1 K by using the Maxwell's relations from the magnetic isotherms. The relative cooling power was increasing from 0.67 to 3.74 J kg À1 with the increases of magnetic field changes from 0-1 to 0-5 T. The observed reversible MCE is related… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
