XRD, CMR, Manganites, Susceptibility, magnetic Properties Curie temperatureAbstract
The substitution of high Tin (Sn) doping concentration by 10%, 20% 30 % and 40% have been made primarily by Solid state reaction (SSR) methods to study structure and magnetic phase properties of (La1-xSnx)1/3Ca2/3MnO3. The XRD, shows all samples in single phase with orthorhombic structure ,the microstructures were studied via scanning electron microscope (SEM), which indicated that grain size increasing as increasing of Sn doping. Magneto-resistivity dependence to the temperature (MR_T ).) was measured by standard four-probe system A decrease in temperature was seen at the phase transition temperature (TP). and the resistivity decreased sharply among substitution Sn2⁺ for La²⁺ ions increases from 10 % to 40 %. The temperature- dependence magneto resistance (M–T) shown the high MR% of the samples were around the TC temperature, which can be explained by enhancement of DE interaction between Mn+3 - Mn+4 ionic.
