通过对热流的精确控制,研究了坡莫合金薄膜的磁热电特性。通过热电压 V-x 和 V-y 的角度和场依赖性,可以在组合的纵向和横向温度场中观察到反常和平面能斯特效应的混合。 Py 的磁化强度和温度梯度之间的相互作用引起了磁化反转过程中反常和平面能斯特效应的复杂场相关行为。
The magnetothermoelectric characteristics of permalloy film have been investigated by exquisite manipulation of heat flow. Through the angle and field dependence of thermal voltages V-x and V-y, the hybrid of the anomalous and the planar Nernst effect can be observed in the combined longitudinal and transverse temperature field. The interplay between the magnetization of Py and the temperature gradient gives rise to the complex field-dependent behaviors of the anomalous and the planar Nernst effect during magnetization reversal.
