Depth profile reconstruction of YCrO3 / CaMnO3 superlattices by near total reflection HAXPES
Abstract
We have determined the depth profile of YCrO3 / CaMnO3 superlattices by HAXPES in near total reflection conditions. YCrO3 / CaMnO3 is prone to exhibit interesting magnetotransport properties owing to the large amount of electron transfer expected between Cr 3+ and Mn 4+. The depth profile was reconstructed by simulation of the rocking curves of the different core levels using the YXRO software and fine tuning of the structural model. The results are globally conformed to scanning transmission electron microscopy and electron energy loss spectroscopy analysis except for the top layer whose structure and stoichiometry are found to be preserved in contrast to microscopy.
