论文摘要

基于稀释的含有1%磁原子的稀释的铁磁PDFE合金,已经观察到对Ferromagnet/Superpoductor/Ferromagnet(FSF)微生物的明显磁化作用。 FSF三层的微观结构不会破坏效果:最明显的曲线是在6-8 UM宽的最小桥梁和10-15 um长的最小桥梁上获得的。在超导转变下方,我们能够通过在PDFE层的磁化磁化标准和AP方向之间切换来控制微杆的临界电流。 FSF-bridge作为磁开关的运行在几个方案中证明了数字状态之间的明显电压辨别或较低的位误差率。

A noticeable magnetoresistive effect has been observed on ferromagnet/superconductor/ferromagnet (FSF) microbridges based on diluted ferromagnetic PdFe alloy containing as small as 1% magnetic atoms. Microstructuring of the FSF trilayers does not destroy the effect: the most pronounced curves were obtained on the smallest bridges of 6-8 um wide and 10-15 um long. Below the superconducting transition we are able to control the critical current of microbridges by switching between P and AP orientations of magnetizations of PdFe layers. The operation of FSF-bridge as a magnetic switch is demonstrated in several regimes providing significant voltage discrimination between digital states or remarkably low bit error rate.
