Research Abstract

In order to develop a novel spin devise the spin-dependent transport properties in quasi two-dimensional superconducting layer have been investigated. The samples composed of a whisker crystal of Bi-system high Tc superconductor and Co thin film were fabricated by photolithography and Ar ion milling. We found that the samples showed the hysteretic field dependence of a critical current and the voltage at a constant bias current by applying magnetic field parallel to layer. The obtained results suggests a potential for the novel spintoronics device application of such hybrid structures.
