摘　　要：高温超导体中电子的自旋和电荷一样重要 .文章对高温超导体的电子结构、磁性相互作用和关于单胞层La1.85Sr0 .15CuO4存在超导态的最新实验结果作了扼要的介绍 ,并指出 。Electron spin is as important as electron′s charge in high\| T c superconductors. In this article we give a brief overview of the electronic structure, magnetic interaction and recent experimental results for superconducting one\|unit\|thick layers of La 1.85 Sr 0.15 CuO 4. We conclude that the effective spin coupling of electrons is responsible for the origin of high\| T c superconductivity.
