Applied Physics A, 129(1), 26.1432-0630http://dx.doi.org/10.1007/s00339-022-06302-5https://hdl.handle.net/20.500.12491/11370Structural, microstructural, magnetic, electrical and magneto-transport properties of La0.7Ca0.18Ba0.12Mn0.95Sn0.05O3 manganite powders, prepared by the solid state method, were investigated. Two quenching processes were performed on the samples: quenching in air and quenching to 77 K in liquid nitrogen. X-ray diffraction patterns refinement revealed that the samples crystallized in the orthorhombic structure. The scanning electron microscopy micrographs presented granular characters. The magnetization vs temperature plot showed a paramagnetic-ferromagnetic transition. The inverse susceptibility chi(-1)(T) deviation from the Curie-Weiss law revealed the existence of the phase above T-C in the nitrogen-quenched sample. The hysteresis cycles reveal that the samples are ferromagnetic at 1.8 K and paramagnetic at 300 K. The resistivity curves exhibit a ferromagnetic-metallic to paramagnetic-insulating transition. The magnetoresistance increased slightly in the sample quenched to 77 K in N-2.eninfo:eu-repo/semantics/closedAccessPerovskite ManganitesQuenchingStructureMagnetotransport PropertiesMagnetic PropertiesDouble-Exchange MechanismArticle10.1007/s00339-022-06302-512911172-s2.0-85144373317Q2WOS:000898816400003Q2
