Interfacial ferromagnetism and atomic structures in high-temperature grown Fe3O4/Pt/Fe3O4 epitaxial trilayers 2019 Access copy available to the general public Unrestricted Induced Pt ferromagnetism in Fe 3 O 4 / Pt / Fe 3 O 4 epitaxial trilayer films has been investigated by means of X-ray magnetic circular dichroism (XMCD) at the Pt L 3, 2-edges at various temperatures from 300 K to 12 K, including the metal-insulator transition temperature of Fe 3 O 4 (T V ~ 114 K). 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. info:eu-repo/grantAgreement/ES/DGA/E26 info:eu-repo/grantAgreement/EC/H2020/734187/EU/Spin conversion, logic storage in oxide-based electronics/SPICOLOST This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 734187-SPICOLOST info:eu-repo/grantAgreement/ES/MINECO/MAT2017-82970-C2 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.286 2019 PHYSICS, APPLIED 70 / 154 = 0.455 2019 Q2 T2 0.728 2019 Physics and Astronomy (miscellaneous) 2019 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Suzuki, M.
