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 ...
Sensitiveness of the ratio between monovacancy and bulk positron lifetimes to the approximations used in the calculations: Periodic behaviour
(Elsevier, 2012-05-09)
Positron lifetimes have been calculated in bulk and monovacancies for most of the elements of the periodic table. Self-consistent and non-self-consistent schemes have been used for the calculation of the electronic structure ...
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 ...
Structural and magnetic properties of Nd-Fe-Mo-(N) melt-spun ribbons with ThMn12 structure
(Elsevier, 2020-06-03)
The influence of quenching rate and nitrogenation in melt-spun Nd1.2Fe10.6Mo1.4 has been investigated in
terms of microstructure, phase formation and magnetic properties. Increasing the quenching rate leads
to smaller ...
Structural and magnetic properties of hexagonal Fe3Sn prepared by non-equilibrium techniques
(Elsevier, 2018-07-29)
We report a thorough structural and magnetic study of Fe3Sn produced either by solid state reaction or by mechanical alloying in order to figure out which of the two techniques is most suitable for obtaining the purest ...
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 ...
Seasonal Correction of Offshore Wind Energy Potential due to Air Density: Case of the Iberian Peninsula
(MDPI, 2019-07-02)
A constant value of air density based on its annual average value at a given location is commonly used for the computation of the annual energy production in wind industry. Thus, the correction required in the estimation ...
The Consequences of Air Density Variations over Northeastern Scotland for Offshore Wind Energy Potential
(MDPI, 2019-07-09)
Hywind-Scotland is a wind farm in Scotland that for many reasons is at the leading edge of technology and is located at a paradigmatic study area for offshore wind energy assessment. The objective of this paper is to compute ...
