At all the temperatures, we observed clear XMCD signals due to Pt ferromagnetism, the amplitude of which was determined to be 0.39 µ B at 300 K and 0.52 µ B at 12 K for the sample with the Pt thickness of ~ 2 nm. Interestingly, these values are comparable to or even greater than those in Pt/3 d-ferromagnetic-metal (Fe, Ni, Co, and Ni 81 Fe 19) junction systems. The results can be interpreted in terms of a possible Fe interdiffusion into the Pt layer and also possible Fe-Pt alloying due to its high-temperature deposition.2019http://zaguan.unizar.es/record/8848910.1063/1.5125761http://zaguan.unizar.es/record/88489oai:zaguan.unizar.es:88489info:eu-repo/grantAgreement/ES/DGA/E26info:eu-repo/grantAgreement/EC/H2020/734187/EU/Spin conversion, logic storage in oxide-based electronics/SPICOLOSTThis project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 734187-SPICOLOSTinfo:eu-repo/grantAgreement/ES/MINECO/MAT2017-82970-C2Journal of Applied Physics 126, 14 (2019), 143903 [11 pp.]All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
