论文摘要
已经使用PT/YIG连接系统在室温到Yig的curie温度下，通过锁定锁定方法研究了旋转层效应（SPE）的温度和YTTRIUM-IRON-GARNET（YIG）厚度依赖性（SPE）。通过使用指数衰减模型分析YIG厚度依赖性，YIG中SPE的特征长度估计在室温附近为0.9 $ $ m，甚至在Curie温度附近几乎恒定。 SPE的高温行为与旋转Seebeck效应的高温行为明显不同，这为显微镜从了解它们之间的相互关系提供了线索。
The temperature and yttrium-iron-garnet (YIG) thickness dependences of the spin Peltier effect (SPE) have been investigated using a Pt/YIG junction system at temperatures ranging from room temperature to the Curie temperature of YIG by the lock-in thermography method. By analyzing the YIG thickness dependence using an exponential decay model, the characteristic length of SPE in YIG is estimated to be 0.9 $μ$m near room temperature and almost constant even near the Curie temperature. The high-temperature behavior of SPE is clearly different from that of the spin Seebeck effect, providing a clue for microscopically understanding the reciprocal relation between them.
