An ANE voltage is observed for [Fe 3 O 4 /Pt] n multilayers, and we further investigated its origin by performing measurements in [Fe 3 O 4 /Pt/Fe 3 O 4 ] trilayers as a function of the Pt thickness. Our results suggest the presence of an interface-induced ANE in the metallic layer, possibly driven by a heat induced subnanometer interdiffusion which affects the nature of the Fe 3 O 4 /Pt interface. Despite this ANE, the spin Seebeck effect is the dominant mechanism for the transverse thermoelectric voltage in the in-plane magnetized configuration, accounting for about 70% of the voltage in the multilayers.2019http://zaguan.unizar.es/record/7884010.1063/1.5063553http://zaguan.unizar.es/record/78840oai:zaguan.unizar.es:78840info:eu-repo/grantAgreement/ES/MINECO/FIS2016-78591-C3-1-R-SKYTRONinfo:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT2017-82970-C2This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 737116-ByAXONinfo:eu-repo/grantAgreement/EUR/H2020/737116-ByAXONThis 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/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 FLAG ERA Graphene Flagship PCIN-2015-111 SOgraphinfo:eu-repo/grantAgreement/EUR/H2020/FLAG ERA Graphene Flagship PCIN-2015-111 SOgraphinfo:eu-repo/grantAgreement/ES/DGA/E26Applied Physics Letters 114, 11 (2019), 113902All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
