La0.7Sr0.3MnO3 in a La0.7Sr0.3MnO3/SrTiO3-(111) heterostructure. This is a part of an electron beam exposure experiment, this spectrum being from the end of the experiment. There are clear signs of beam damage, seen with an increase in the L3/L2-ratio, and energy shift towards lower energy loss of the L3 and L2 peaks.
