Polarized XAFS study on the ultrathin Pt/Co/Pt trilayers modified with short light pulses

The Pt/Co/Pt trilayers irradiated with light pulses of different characteristics and showing the out-of-plane magnetization were investigated by means of the polarized X-ray absorption fine structure technique. The results of studies revealed that the irradiation introduces Co-Pt intermixing and strain in the layers. The Co-Pt alloys composition in the irradiated layer was found to be correlated with the magnetization remanence.
