Spin diffusion length of Permalloy using spin absorption in lateral spin valves
Edurne Sagasta, Yasutomo Omori, Miren Isasa +3
We employ the spin absorption technique in lateral spin valves to extract the spin diffusion length of Permalloy (Py) as a function of temperature and resistivity. A linear depende…
Tuning the spin Hall effect of Pt from the moderately dirty to the superclean regime
Edurne Sagasta, Yasutomo Omori, Miren Isasa +5
We systematically measure and analyze the spin diffusion length and the spin Hall effect in Pt with a wide range of conductivities using the spin absorption method in lateral spin…
Spin Hall magnetoresistance as a probe for surface magnetization in Pt/CoFeO bilayers
Miren Isasa, Saül Vélez, Edurne Sagasta +6
We study the spin Hall magnetoresistance (SMR) in Pt grown on CoFeO (CFO) ferrimagnetic insulating (FMI) films. A careful analysis of the angle-dependent…
Absence of magnetic proximity effects in magnetoresistive Pt/CoFe2O4 hybrid interfaces
M. Valvidares, N. Dix, M. Isasa +10
Ultra-thin Pt films grown on insulating ferrimagnetic CoFe2O4 (111) epitaxial films display a magnetoresistance upon rotating the magnetization of the magnetic layer. We report her…
Hanle Magnetoresistance in Thin Metal Films with Strong Spin-Orbit Coupling
Saül Vélez, Vitaly N. Golovach, Amilcar Bedoya-Pinto +7
We report measurements of a new type of magnetoresistance in Pt and Ta thin films. The spin accumulation created at the surfaces of the film by the spin Hall effect decreases in a…
Spin transport enhancement by controlling the Ag growth in lateral spin valves
Miren Isasa, Estitxu Villamor, Lorenzo Fallarino +6
The role of the growth conditions in the spin transport properties of silver (Ag) have been studied by using lateral spin valve structures. By changing the deposition conditions of…
Origin of inverse Rashba-Edelstein effect at Cu/Bi interface using lateral spin valves
M. Isasa, M. C. Martínez-Velarte, E. Villamor +9
The spin transport and spin-to-charge current conversion properties of bismuth are investigated using permalloy/copper/bismuth (Py/Cu/Bi)lateral spin valve structures. The spin cur…
Temperature dependence of spin diffusion length and spin Hall angle in Au and Pt
Miren Isasa, Estitxu Villamor, Luis E. Hueso +2
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…
Modulation of pure spin currents with a ferromagnetic insulator
Estitxu Villamor, Miren Isasa, Saül Vélez +5
We propose and demonstrate spin manipulation by magnetically controlled modulation of pure spin currents in cobalt/copper lateral spin valves, fabricated on top of the magnetic ins…
Spin Hall magnetoresistance at Pt/CoFe2O4 interfaces and texture effects
Miren Isasa, Amilcar Bedoya-Pinto, Saül Vélez +5
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 t…
Temperature dependence of spin polarization in ferromagnetic metals using lateral spin valves
Estitxu Villamor, Miren Isasa, Luis E. Hueso +1
A high reproducibility in the performance of cobalt/copper and permalloy/copper lateral spin valves with transparent contacts is obtained by optimizing the interface quality and th…

Estitxu Villamor, Miren Isasa, Luis E. Hueso +1
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 f…
