| Outline of Final Research Achievements |
In this research project, we aimed to develop novel spintronic devices using atomically-thin superconducting films. We fabricated atomically-thin NbSe2 wires and included them into spin transport devices. A clear inverse spin Hall effect was detected above the superconducting transition temperature of NbSe2 nanowire. We also fabricated high-temperature superconductor Bi2Sr2CaCu2O8+x thin film devices, in order to extend the variety of superconducting materials which can be mounted on spintronic devices. In addition, we irradiated a surface acoustic wave with the wavelength of about 1 micrometer to an atomically-thin NbSe2 device on the LiNbO3 substrate and found a negative resistance within the superconducting gap, which was not measured for conventional superconductors. The above results are a big step toward the realization of the future atomic layer spintronic devices.
