WebMay 23, 2011 · Spin pumping has been previously detected indirectly by increased damping due to the leakage of energy and angular momentum out of the ferromagnet into the conductor [9], spin back-flow induced voltages [10], and the inverse spin Hall effect (ISHE) [11], in which a spin current induces a transverse electromotive force in a normal metal … WebSpin valves based on materials in which the spin-flip is suppressed by the spatial separation of charge carriers, while maintaining electric neutrality in the valve volume, are …
WebJun 28, 2024 · The spin-to-charge current conversion, occurring at the graphene layer, is explained by the extrinsic spin-orbit interaction induced by the proximity effect with the ferromagnetic layer. WebThe ultrafast laser pulses effectively enhance the interfacial spin pumping effect via tuning the spin diffusion length of the adjacent Ta layer, from 2.4 to 7.1 nm. Our findings provide insights ...
WebThe spin dynamic process of the IrMn/CoFe system has been investigated by the time-resolved magneto-optical Kerr effect. It is found that both spin pumping and the interfacial exchange spring effect between IrMn and CoFe layers contribute to the total effective Gilbert damping. With the increase in IrMn layer thickness (tIrMn), the saturated damping factor … Spin pumping is a method of generating a spin current, the spintronic analog of a battery in conventional electronics. In order to make a spintronic device, the primary requirement is to have a system that: can generate a current of spin-polarized electrons andis sensitive to the spin polarization.
