X-Ray Photoelectron Spectra of La0.67Ca0.33MnO3 Processed by EATPAH Technique.

La0.67Ca0.33MnO3 (LCMO) colossal magnetoresistance (CMR) materials were sintered to highly dense products by an extended arc thermal plasma assisted heating (EATPAH) technique within a short sintering time of 2.5 minutes as compared to conventional long range heating schedule (few hours of time). 2.5 minutes plasma sintered LCMO showed enhanced Tc (272 K), which is closed to TIM (275 K) [1] as compared to the conventional sintered LCMO sample. Specimens are analyzed by X-ray Photoelectron Spectra (XPS) and electron probe microstructure analysis (EPMA) to get idea on elemental distribution and valence spectra of all the elements present in the specimen. The binding energy of La, Ca & Mn are analogous to the conventional sintered LCMO and to the reference spectra [2]. [ABSTRACT FROM AUTHOR]
