Growth mechanical of (La,A)MnO3,A=Ca,Sr And Film thickness effect of Colossal magnetoresistance(CMR)

Abstract
There has been much interest in colossal magnetoresistance in doped maganite peroviskite meterials.(La,A)MnO3 thin film have been fabricated by off-axis RF magnetron sputtering techhique.
The Growth mechanical of (La,A)MnO3 A=Ca,Sr in Different growth temperatures on substrate and different annealing temperatures reveals the observably different results on its structure and electrical transport properties.
Due to the lattice mismatch between substrates and bulk,strain has been a important factors of magnetic resistance and electrical properties.
Different thickness of La0.67Ca0.33MnO3 thin film were grown on (001)SrTiO3 and(001)MgO substrates at growth temperature 750 degree C ,it has shown systematic variations to film thickness in magnetic and electrical transport properties.
