Modulation of spin Seebeck effect by hydrogenation
نویسندگان
چکیده
We demonstrate the modulation of spin Seebeck effect (SSE) by hydrogenation in Pd/YIG bilayers. In presence 3% hydrogen gas, SSE voltage decreases more than 50% from magnitude observed pure Ar gas. The is reversible, but recovery to prehydrogenation value takes a few days because long time constant desorption. also that Hall magnetoresistance identical sample reduces significantly with exposure, supporting current signals originates Pd/YIG.

Antiferromagnetic Spin Seebeck Effect.
We report on the observation of the spin Seebeck effect in antiferromagnetic MnF_{2}. A device scale on-chip heater is deposited on a bilayer of MnF_{2} (110) (30 nm)/Pt (4 nm) grown by molecular beam epitaxy on a MgF_{2} (110) substrate. Using Pt as a spin detector layer, it is possible to measure the thermally generated spin current from MnF_{2} through the inverse spin Hall effect. The low ...
متن کاملLength Scale of the Spin Seebeck Effect.
We investigate the origin of the spin Seebeck effect in yttrium iron garnet (YIG) samples for film thicknesses from 20 nm to 50 μm at room temperature and 50 K. Our results reveal a characteristic increase of the longitudinal spin Seebeck effect amplitude with the thickness of the insulating ferrimagnetic YIG, which levels off at a critical thickness that increases with decreasing temperature....
متن کاملDomain wall motion by the magnonic spin Seebeck effect.
The recently discovered spin Seebeck effect refers to a spin current induced by a temperature gradient in a ferromagnetic material. It combines spin degrees of freedom with caloric properties, opening the door for the invention of new, spin caloritronic devices. Using spin model simulations as well as an innovative, multiscale micromagnetic framework we show that magnonic spin currents caused b...
متن کاملIntrinsic spin Seebeck effect in Au/YIG.
The acute magnetic proximity effects in Pt/YIG compromise the suitability of Pt as a spin current detector. We show that Au/YIG, with no anomalous Hall effect and a negligible magnetoresistance, allows the measurements of the intrinsic spin Seebeck effect with a magnitude much smaller than that in Pt/YIG. The experiment results are consistent with the spin polarized density functional calculati...
