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, ...
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)
Spin Hall magnetoresistance at Pt/CoFe2O4 interfaces and texture effects
(American Institute of Physics, 2014-10)
We report magnetoresistance measurements on thin Pt bars grown on epitaxial (001) and (111) CoFe2O4 (CFO) ferrimagnetic insulating films. The results can be described in terms of the recently discovered spin Hall ...
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 ...
Kubo-Bastin approach for the spin Hall conductivity of decorated graphene
(2016-05-31)
Theoretical predictions and recent experimental results suggest one can engineer spin Hall effect in graphene by enhancing the spin-orbit coupling (SOC) in the vicinity of an impurity. We use a Chebyshev expansion of the ...
Study of the longitudinal spin Seebeck effect in hybrid structures with yttrium iron garnet and various metallic materials
(Universidade Federal de Pernambuco, 2015)
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 ...
Efeito hall de spin inverso em multicamadas de Ta/NiFe/FeMn/Ta
(Universidade Federal de Santa MariaBrasilFísicaUFSMPrograma de Pós-Graduação em FísicaCentro de Ciências Naturais e Exatas, 2017-10-27)
In the present thesis, the generation of a dc voltage in exchange-biased Ta/NiFe/FeMn/Ta
multilayers at ferromagnetic resonance was investigated. This dc signal is related to two distinct
phenomena, namely, the spin ...
Spin Hall Effect in Symmetric Wells with Two Subbands
(SPRINGER, 2010)
We investigate the spin Hall conductivity sigma (xy) (z) of a clean 2D electron gas formed in a two-subband well. We determine sigma (xy) (z) as arising from the inter-subband induced spin-orbit (SO) coupling eta (Calsaverini ...
