在常规超导体,库柏对被声子调停,它是在声子和电子的电荷性质之间的关联仅仅被需要的一个过程。然而,超导性能也从基本刺激的另外的类型被导出。旋转变化可以证明是能调停的最有希望的候选人如此的异乎寻常的超导性。在一些象 cuprates,基于 Fe 的超导体和重费米子的超导体那样的重要系统,尽管仍然有许多争论,旋转变化在他们的超导性的机制起一个关键作用。在这份报纸,我们将在在旋转变化和超导性之间的关联上给简短评论。
In the conventional superconductors, the Cooper pairs are mediated by phonons, which is a pro- cess where only the correlations between the phonons and the charge properties of the electrons are needed. However, superconductivity can also be derived from other types of elementary excitations. The spin fluctuations are arguably the most promising candidate that can mediate such unconventional superconductivity. In some of the important systems such as cuprates, Fe-based superconductors and heavy-fermion superconductors, spin fluctuations play a key role in the mechanism of their superconductivity although there are still many debates. In this paper, we will give a brief review on the correlation between the spin fluctuations and superconductivity.
