热电势，即所谓的塞贝克效应，是热到电的转换，并且是由于传导电子携带的熵。在强关联电子系统和近藤材料中，自旋涨落在传导电子中产生熵，导致巨大的热电势。最近，人们发现了自旋塞贝克效应，它反映了磁性材料中通过自旋电流的转换。的机制进行检查，并解释了各种实验。
The thermopower, the so-called Seebeck effect, is the conversion of heat to electricity and is due to the entropy carried by conduction electrons. In strongly-correlated electron systems and Kondo materials, spin fluctuation is shown to bring about an entropy in conduction electrons and to result in a giant thermopower. Recently, the spin Seebeck effect, which reflects the conversion via the spin current in magnetic materials, was discovered. The mechanism is examined and a variety of experiments are explained.
