Contribution of defects to the spin relaxation in copper nanowires
(Americal Physical Society, 2013-03-18)
The contributions to the spin relaxation in copper (Cu) nanowires are quantified by carefully analyzing measurements of both charge and spin transport in lateral spin valves as a function of temperature and thickness. The ...
Temperature dependence of spin diffusion length and spin Hall angle in Au and Pt
(Americal Physical Society, 2015-01-05)
We have studied the spin transport and the spin Hall effect as a function of temperature for platinum (Pt) and gold (Au) in lateral spin valve structures. First, by using the spin absorption technique, we extract the spin ...
Temperature dependence of spin polarization in ferromagnetic metals using lateral spin valves
(Americal Physical Society, 2013-11-15)
Spin injection properties of ferromagnetic metals are studied and are compared by using highly reproducible cobalt/copper and permalloy/copper lateral spin valves (LSVs) with transparent contacts, fabricated with a careful ...
Simultaneous detection of the spin-Hall magnetoresistance and the spin-Seebeck effect in platinum and tantalum on yttrium iron garnet
(Americal Physical Society, 2014-11-26)
The spin-Seebeck effect (SSE) in platinum (Pt) and tantalum (Ta) on yttrium iron garnet has been investigated by both externally heating the sample (using an on-chip Pt heater on top of the device) and by current-induced ...
Spin Hall magnetoresistance at Pt/CoFe2O4 interfaces and texture effects
(AIP publishing, 2014-10-08)
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 ...
Spin transport enhancement by controlling the Ag growth in lateral spin valves
(IOP publishing, 2015-04-21)
The role of the growth conditions onto the spin transport properties of silver (Ag) have been studied by using lateral spin valve structures. By changing the deposition conditions of Ag from polycrystalline to epitaxial ...
