中文摘要：

我们报导 La60Fe30Al10 金属性的玻璃在它的超导的转变温度下面作为一个垂直磁场的功能在它的微分抵抗有清楚的、可再现的、周期的变化。摆动时期对应于超导的流动量。观察现象与高方面比率和一致取向在圆柱的 La nanorod 从 Little-Parks-like 抵抗摆动发源在带子表面上猛抛。高度面向的 La nanocrystals 为把众多的超导的电路集成到一个单个薄片在一项灵活玻璃底层提议上准备了一个机会。

英文摘要：

We report that La60Fe30Al10 metallic glass has clear,reproducible,periodic variation in its differential resistance as a function of a perpendicular magnetic field below its superconducting transition temperature. The oscillation period corresponds to a superconducting flux quantum. The observed phenomena originate from the Little-Parks-like resistance oscillations in the cylindrical La nanorod with a high aspect ratio and uniform orientation precipitated on the ribbon surface. The highly-oriented La nanocrystals prepared on a flexible glass substrate offer an opportunity for integrating numerous superconducting circuits into a single chip.
