Thermoelectric performance of spin Seebeck effect in Fe3O4/Pt-based thin film heterostructures 2016 Access copy available to the general public Unrestricted We report a systematic study on the thermoelectric performance of spin Seebeck devices based on Fe3O4/Pt junction systems. We explore two types of device geometries: a spin Hall thermopile and spin Seebeck multilayer structures. The spin Hall thermopile increases the sensitivity of the spin Seebeck effect, while the increase in the sample internal resistance has a detrimental effect on the output power. We found that the spin Seebeck multilayers can overcome this limitation since the multilayers exhibit the enhancement of the thermoelectric voltage and the reduction of the internal resistance simultaneously, therefore resulting in significant power enhancement. This result demonstrates that the multilayer structures are useful for improving the thermoelectric performance of the spin Seebeck effect. info:eu-repo/grantAgreement/ES/DGA/E26-304043 info:eu-repo/grantAgreement/ES/MINECO/MAT2011-27553-C02 info:eu-repo/grantAgreement/ES/MINECO/PRI-PIBJP-2011-0794 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.335 2016 MATERIALS SCIENCE, MULTIDISCIPLINARY 46 / 275 = 0.167 2016 Q1 T1 PHYSICS, APPLIED 23 / 147 = 0.156 2016 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 28 / 87 = 0.322 2016 Q2 T1 2.177 2016 Materials Science (miscellaneous) 2016 Q1 Engineering (miscellaneous) 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0001-5939-6415 Anadón, A.
