Detecção elétrica de correntes de spin em sistemas nano-estruturados
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2016-12-15)
Spintronics is an emergent research field that seeks a better understanding of the role of electronic spin in solid state physics. Exploring electrons’ charge and spin, significant technological advances might be achieved, ...
Single-parameter spin-pumping in driven metallic rings with spin-orbit coupling
(2014)
We consider the generation of a pure spin-current at zero bias voltage with a single time-dependent potential. To such end we study a device made of a mesoscopic ring connected to electrodes and clarify the interplay between ...
The role of metallic nanoparticles in the enhancement of the spin Hall magnetoresistance in YIG/Pt thin films
(Journal of Magnetism and Magnetic Materials, 2018)
Magnetorresistência e correntes de spin em Multicamadas de Ni81Fe19/ZnO/Pd
(Universidade Federal de Santa MariaBrasilFísicaUFSMPrograma de Pós-Graduação em FísicaCentro de Ciências Naturais e Exatas, 2017-03-02)
In this work, we analyzed samples of thin films Ni81Fe19 and Pd with ZnO spacer. Ni81Fe19
is a ferromagnet with a low saturation magnetic field. Pd is a normal metal with high spinorbit
coupling, much used in spin Hall ...
Alternating spin-polarized current induces parametric resonance in spin valves
(2015)
Ferromagnetic systems under the influence of spin-polarized currents exhibit rich spatiotemporal dynamics at nanoscales. We study spin-transfer nano-oscillators driven by the combination of alternating and direct spin-polarized ...
Spin pumping and inverse spin Hall effect in antiferromagnetic exchange coupled [Co/Ru/Co]/Pt heterostructures
(American Institute of Physics, 2017-01)
We report the observation of spin pumping and inverse spin Hall effects in antiferromagnetically coupled [Co/Ru/Co]/Pt heterostructures. The “spin-flop” magnetization process observed in antiferromagnetically exchange ...
Spin polarization in the Hubbard model with Rashba spin-orbit coupling on a ladder
(American Physical Society, 2013-07)
The competition between on-site Coulomb repulsion and Rashba spin-orbit coupling (RSOC) is studied on two-leg ladders by numerical techniques. By studying persistent currents in closed rings by exact diagonalization, it ...
University Spin-Offs: The past, the present, and the future
(2022)
Purpose of this paper: This paper examines the past and present of the university spin-off (USO) phenomenon by identifying research findings and synthesizing different spin-off practices from around the globe. The evolution ...
Study of the longitudinal spin Seebeck effect in hybrid structures with yttrium iron garnet and various metallic materials
