La0.7Sr0.3MnO3 Thin Film, Electron Beam Damage Formula: La0.7Sr0.3MnO3 Core Loss

Submitted by magnunor, August 27, 2016.

Author Comments: La0.7Sr0.3MnO3 in a La0.7Sr0.3MnO3/LaFeO3/SrTiO3-(111) heterostructure. This is a part of an electron beam exposure experiment, this spectrum being after the exposure. There are clear signs of beam damage, due to oxygen having been removed from the material.
