利用邻近效应隧穿谱研究了顺磁-铁磁转变过程中的交换增强电子-电子相互作用。通过求解顺磁态和铁磁态的Usadel方程，由隧道谱推导出电子自旋涨落耦合常数和交换场。
The exchange-enhanced electron-electron interactions at the paramagnetic-ferromagnetic transition were studied experimentally via proximity effect tunneling spectroscopy. By solving the Usadel equations in both the paramagnetic and ferromagnetic states, the electron-spin fluctuation coupling constant and the exchange field are derived from the tunneling spectra.
