论文摘要
磁场调谐的超导体向绝缘体转变，在一种新型的颗粒超导乳化剂的杂种系统中，沉积在氧化物薄膜上，该膜沉积在低磁场处的全局超导性。我们已经使用退火来调整耦合，只是位于抑制底层内的超导性的边界线上，这也接近Inox的金属绝缘体过渡。混合系统在H-sit上方表现出“巨大”磁性，其临界行为表现出库珀对和涡旋之间的二元性。
Magnetic-field tuned superconductor to insulator transition was observed in a novel hybrid system of granular superconducting indium, deposited on indium oxide thin film, which exhibits global superconductivity at low magnetic fields. We have used annealing to tune the coupling to lie just at the borderline where superconductivity in the underlying InOx is suppressed, which is also close to the metal-insulator transition of the InOx. The hybrid system exhibits a "giant" magnetoresistance above the H-SIT, with critical behavior that manifests the duality between Cooper pairs and vortices.
