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, ...
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 ...
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 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 ...
Pure spin current manipulation in antiferromagnetically exchange coupled heterostructures
(American Institute of Physics, 2018-03-28)
We present a model to describe the spin currents generated by ferromagnet/spacer/ferromagnet exchange coupled trilayer systems and heavy metal layers with strong spin-orbit coupling. By exploiting the magnitude of the ...
Multiferroicity in an organic charge-transfer salt that is suggestive of electric-dipole-driven magnetism
(2012-09-01)
Multiferroics, showing simultaneous ordering of electrical and magnetic degrees of freedom, are remarkable materials as seen from both the academic and technological points of view. A prominent mechanism of multiferroicity ...

Magnetoelectric tuning of the inverse spin-Hall effect
(American Institute of Physics, 2017-05-09)
We demonstrate in this article that the magnetoelectric (ME) mechanism can be exploited to control the spin current emitted in a spin pumping experiment using moderate electric fields. Spin currents were generated at the ...
