论文摘要
我们通过PD/YIG双层中的氢化来证明自旋塞贝克效应（SSE）的调节。在存在3％氢气的情况下，SSE电压比在纯AR气体中观察到的幅度降低了50％以上。 SSE电压的调节是可逆的，但是由于氢脱附的长时间常数，SSE电压恢复为氢化值需要几天。我们还证明，相同样品的自旋霍尔磁磁性会随氢的暴露显着降低，这支持观察到的自旋电流信号的调节源自PD/YIG的氢化。
We demonstrate the modulation of spin Seebeck effect (SSE) by hydrogenation in Pd/YIG bilayers. In the presence of 3% hydrogen gas, SSE voltage decreases by more than 50% from the magnitude observed in pure Ar gas. The modulation of the SSE voltage is reversible, but the recovery of the SSE voltage to the prehydrogenation value takes a few days because of a long time constant of hydrogen desorption. We also demonstrate that the spin Hall magnetoresistance of the identical sample reduces significantly with hydrogen exposure, supporting that the observed modulation of spin current signals originates from hydrogenation of Pd/YIG.
