LSMO Perovskite Formula: (La0.7,Sr0.3)MnO3 Core Loss

Submitted by Dominique Imhoff, March 4, 2008.

Source / Purity: Perovskite multilayers UMP CNRS-Thales Palaiseau France (laser ablation)

Author Comments: Background removed calibration : 1- XAS energy reference from standard similar LSMO (maximum of MnL3 peak) 2- energy dispersion calibration of the detector from two peaks reference in low and core loss areas (STO substrate area in the multimayer system). see also LaM,OK Analyst: imhoff. Temperature: Room.
