摘要

基于自旋极化方法研究了三维液态过渡金属系列的电阻率和热功率。这意味着原子磁矩的存在和电阻率的双带传导模型的使用。计算得到的电阻率是迄今为止在齐曼格式中得到的最低的,与实验结果的吻合度比与经典的非极化计算结果的吻合度更好。尽管在非磁性结果方面有所改进,但热电功率值并没有达到在电阻率方面观察到的一致程度。

Electronic transport properties in the liquid 3d transition-metal series
Abstract The resistivities and thermopowers of the liquid 3d transition-metal series have been investigated within Ziman's formula based on a spin-polarized approach. This implies the existence of atomic magnetic moments and the use of a two-band conduction model for the resistivity. The calculated resistivities are the lowest obtained until now within the Ziman scheme and better agreement with experiment has been found than with the classical non-polarized calculations. In spite of the improvement with respect to the non-magnetic results, the thermoelectric power values do not attain the degree of agreement observed for the resistivities.
