Ferromagnetic Insulators for Spin-Polarized Electron Tunneling Studies

他们将(1)研究EUS和其他铁磁绝缘体与金属接触并作为薄膜隧道结的隧道势垒的系统学；(2)使用这项新技术，首次对许多金属中的自旋轨道和费米液体效应进行隧道测量；(3)寻找重电子和高温超导体中的自旋效应；(4)研究了H=0到30T时与铁磁金属的交换效应、磁畴和表面的磁效应。本程序将(1)给出铁磁绝缘体与超导体、铁磁金属和顺磁金属之间的交换效应；(2)给出电子通过铁磁绝缘体隧穿的定量图像；(3)允许进行新的测量，给出正常金属中超导、铁磁性和电子自旋效应的基本结果。

They will (1) study the systematics of EuS and other ferromagnetic insulators in contact with metals and as tunnel barriers of thin film tunnel junctions; (2) use the new technique, which allows for the first time tunneling measurements of spin-orbit and Fermi-liquid effects in many metals; (3) look for spin effects in heavy-electron and high temperature superconductors; (4) study the exchange effects with ferromagnetic metals, magnetic domains, and magnetic effects at surfaces for H = 0 to 30 T. This program will (1) give an understanding of exchange effects between ferromagnetic insulators and superconductors, ferromagnetic metals, and paramagnetic metals; (2) give a quantitative picture of electron tunneling through ferromagnetic insulators; (3) permit new measurements giving fundamental results in superconductivity, ferromagnetism, and electron-spin effects in normal metals.
