(orcid)0000-0001-5939-6415 Spin-orbit torque from the introduction of Cu interlayers in Pt/Cu/Co/Pt nanolayered structures for spintronic devices 2021 Access copy available to the general public Unrestricted Spin currents can modify the magnetic state of ferromagnetic ultrathin films through spin-orbit torque. They may be generated by means of spin-orbit interactions by either bulk or interfacial phenomena. Electrical transport measurements reveal a 6-fold increase of the spin-orbit torque accompanied by a drastic reduction of the spin Hall magnetoresistance upon the introduction of an ultrathin Cu interlayer in a Pt/Cu/Co/Pt structure with perpendicular magnetic anisotropy. We analyze the dependence of the spin Hall magnetoresistance with the thickness of the interlayer, ranging from 0.5 to 15 nm, in the frame of a drift diffusion model that provides information on the expected spin currents and spin accumulations in the system. The results demonstrate that the major responsibility of both effects is spin memory loss at the interface. The enhancement of the spin-orbit torque when introducing an interlayer opens the possibility to design more efficient spintronic devices based on materials that are cheap and abundant such as copper. More specifically, spin-orbit torque magnetic random access memories and spin logic devices could benefit from the spin-orbit torque enhancement and cheaper material usage presented in this study. info:eu-repo/grantAgreement/ES/MINECO/FIS2016-78591-C3-1-R-SKYTRON info:eu-repo/grantAgreement/ES/MINECO/PCI2019-111867-2-FLAG ERA 3-SOgraphMEM info:eu-repo/grantAgreement/ES/MINECO/PGC2018-098265-B-C31 info:eu-repo/grantAgreement/ES/MINECO/PGC2018-098613-B-C21-SpOrQuMat info:eu-repo/grantAgreement/ES/MINECO/RTI2018-097895-B-C42-FUN-SOC info:eu-repo/grantAgreement/ES/MINECO/SEV-2016-0686 info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 6.14 2021 MATERIALS SCIENCE, MULTIDISCIPLINARY 101 / 344 = 0.294 2021 Q2 T1 NANOSCIENCE & NANOTECHNOLOGY 46 / 108 = 0.426 2021 Q2 T2 1.178 2021 Materials Science (miscellaneous) 2021 Q1 7.2 2021 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Guerrero, R.
