Co/Nb/Co低场超导自旋开关

Co/Nb/Co low field superconducting spin switch

G. Carapella, F. Russo, G. Costabile

摘要:

我们报告的实验超导自旋开关的基础上,技术相关的材料元素铁磁钴和元素超导铌。Co/Nb/Co结构具有反转自旋开关效应,可以在液氦温度下工作,在较弱的外加磁场下可以从超导态转变为正常态。在此讨论了作为温度和磁场函数的相关临界电流以及超导态或电阻态的制备。

英文摘要:

We report experiments on a superconducting spin switch based on technologically relevant materials as elemental ferromagnetic Co and elemental superconducting Nb. The Co/Nb/Co structure exhibits inverse spin switch effect, can be operated at liquid helium temperature and can switch from superconductive to normal state in rather weak applied magnetic fields. Relevant critical currents as a function of temperature and magnetic field as well as preparation of superconductive or resistive state are addressed here.
