摘要:

本文提出了一种新的自旋塞贝克效应的测量技术,其中用于检测的正常金属层同时用作电阻加热器和温度计。我们展示了如何测量的总信号的各种贡献可以解开,允许提取的电压信号仅由自旋塞贝克效应引起的。为此,我们进行了测量的外部磁场强度和它的方向的函数。我们发现,该效果的比例与诱导的温度上升,如预期的自旋塞贝克效应的线性。

英文摘要:

A new measurement technique for the spin Seebeck effect is presented, wherein the normal metal layer used for its detection is exploited simultaneously as a resistive heater and thermometer. We show how the various contributions to the measured total signal can be disentangled, allowing to extract the voltage signal solely caused by the spin Seebeck effect. To this end we performed measurements as a function of the external magnetic field strength and its orientation. We find that the effect scales linearly with the induced rise in temperature, as expected for the spin Seebeck effect.
