s-f交换作用和s-s电子交换作用对热导率和热电势的影响

考虑4f壳层未填满的稀土金属的s-f交换作用，利用Feynman图方法，讨论了传统的电子－声子耦合s-f交换作用和电子交换作用的影响，并定量估计了s-f交换作用与电子－电子交换作用对热导率和热电势的影响。

Influence of s-f exchange effect and s-s electron exchange effect on the thermal conductivity and thermoelectric power in a rare earth metal

Based on the s-d interaction model, it is considered that the influence of s-f exchange effect and electron exchange effect on thermal conductivity and thermoelectric power by using Feynman diagram method t and guanti-tatively estimate the influence on thermal conductivity and thermoelectric power due to s-f exchange effect and electron-electron exchange effect. The results show that the value of thermal conductivity and thermoelectric power of phonon is the biggest part, the value which come from the exchange effect and electron exchange effect is much smaller than that of phonon, and the conclusion can be got: the influence coming from s-f exchange interaction and s-s electron exchange interaction on thermal electronic power is bigger than that on thermoelectric power.
