Layer-resolved magnetic moments in Ni/Pt multilayers

The magnetic moments in Ni/Pt multilayers are thoroughly studied by combini ng experimental and ab initio theoretical techniques. SQUID magnetometry pr obes the samples' magnetizations. X-ray magnetic circular dichroism separat es the contribution of Ni and Pt and provides a layer-resolved magnetic mom ent profile for the whole system. The results are compared to band-structur e calculations. Induced Pt magnetic moments localized mostly at the interfa ce are revealed. No magnetically "dead" Ni layers are found. The magnetizat ion per Ni volume is slightly enhanced compared to bulk NiPt alloys.
