Tuning Coherent-Phonon Heat Transport in LaCoO/SrTiO Superlattices
D. Bugallo, E. Langenberg, E. Carbó-Argibay +6
Accessing the regime of coherent phonon propagation in nanostructures opens enormous possibilities to control the thermal conductivity in energy harvesting devices, phononic circui…
Transition of laser-induced terahertz spin currents from torque- to conduction-electron-mediated transport
Pilar Jiménez-Cavero, Oliver Gueckstock, Lukáš Nádvorník +16
Spin transport is crucial for future spintronic devices operating at bandwidths up to the terahertz (THz) range. In F|N thin-film stacks made of a ferro/ferrimagnetic layer F and a…
Interface-induced anomalous Nernst effect in Fe3O4/Pt-based heterostructures
R. Ramos, T. Kikkawa, A. Anadón +8
We have studied the anomalous Nernst effect (ANE) in [Fe3O4/Pt]-based heterostructures, by measuring the ANE-induced electric field with a magnetic field applied normal to the samp…
Large spin-mixing conductance in highly Bi-doped Cu thin films
Sandra Ruiz-Gómez, Aída Serrano, Rubén Guerrero +12
Spin Hall effect provides an efficient tool for the conversion of a charge current into a spin current, opening the possibility of producing pure spin currents in non-magnetic mate…
Terahertz spin currents and inverse spin Hall effect in thin-film heterostructures containing complex magnetic compounds
T. Seifert, U. Martens, S. Günther +20
Terahertz emission spectroscopy of ultrathin multilayers of magnetic and heavy metals has recently attracted much interest. This method not only provides fundamental insights into…
Thermoelectric performance of spin Seebeck effect in Fe3O4/Pt-based thin film heterostructures
R. Ramos, A. Anadon, I. Lucas +6
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 th…
Observation of huge thermal spin currents in magnetic multilayers
R. Ramos, T. Kikkawa, M. H. Aguirre +11
Thermal spin pumping constitutes a novel mechanism for generation of spin currents; however their weak intensity constitutes a major roadblock for its usefulness. We report a pheno…
Observation of the spin Seebeck effect in epitaxial Fe3O4 thin films
R. Ramos, T. Kikkawa, K. Uchida +8
We report the first experimental observation of the spin Seebeck effect in magnetite thin films. The signal observed at temperatures above the Verwey transition is a contribution f…
