We propose to investigate the magnetic response of heterostructure composed of thin superconduct-ing films deposited on semiconductors or semimetals with strong spin-orbit inter-action (SOI). The temperature dependence and possible anisotropies of the superfluid stiffness will be determined. We will further study the effect of the SOI individual Josephson junctions and Josephson networks that are based on proximity coupling through crystals with strong SOI, and image the supercurrent distribution using scanning Hall microscopy.

我们拟研究沉积在具有强自旋轨道相互作用（SOI）的半导体或半金属上的超导体薄膜异质结构的磁响应。将确定超流体刚度的温度依赖性和可能的各向异性。我们将进一步研究基于强SOI晶体邻近耦合的SOI单个Josephson结和Josephson网络的影响，并使用扫描霍尔显微镜成像超电流分布。
