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…
Interfacial mechanism in the anomalous Hall effect of Co/BiO bilayers
Edurne Sagasta, Juan Borge, Luis Esteban +5
Oxide interfaces are a source of spin-orbit coupling which can lead to novel spin-to-charge conversion effects. In this work the contribution of the BiO interface to the an…
Relation between spin Hall effect and anomalous Hall effect in 3 ferromagnetic metals
Yasutomo Omori, Edurne Sagasta, Yasuhiro Niimi +4
We study the mechanisms of the spin Hall effect (SHE) and anomalous Hall effect (AHE) in 3 ferromagnetic metals (Fe, Co, permalloy (NiFe; Py), and Ni) by varying t…
Detection of the interfacial exchange field at a ferromagnetic insulator-nonmagnetic metal interface with pure spin currents
P. K. Muduli, M. Kimata, Y. Omori +3
At the interface between a nonmagnetic metal (NM) and a ferromagnetic insulator (FI) spin current can interact with the magnetization, leading to a modulation of the spin current.…
Unveiling the mechanisms of the spin Hall effect in Ta
Edurne Sagasta, Yasutomo Omori, Saül Vélez +7
Spin-to-charge current interconversions are widely exploited for the generation and detection of pure spin currents and are key ingredients for future spintronic devices including…
Strong Suppression of the Spin Hall Effect in the Spin Glass State
Y. Niimi, M. Kimata, Y. Omori +5
We have measured spin Hall effects in spin glass metals, CuMnBi alloys, with the spin absorption method in the lateral spin valve structure. Far above the spin glass temperature Tg…
Inverse spin Hall effect in a closed loop circuit
Y. Omori, F. Auvray, T. Wakamura +3
We present measurements of inverse spin Hall effects (ISHEs) in which the conversion of a spin current into a charge current via the ISHE is detected not as a voltage in a standard…
Extrinsic spin Hall effects measured with lateral spin valve structures
Y. Niimi, H. Suzuki, Y. Kawanishi +4
The spin Hall effect (SHE), induced by spin-orbit interaction in nonmagnetic materials, is one of the promising phenomena for conversion between charge and spin currents in spintro…
