We review electronic transport in superconducting junctions with Sr${}_2$RuO${}_4$. Transport measurements provide evidence for chiral domain walls and, therefore, chiral superconductivity in superconducting Sr${}_2$RuO${}_4$, but so far, the symmetry of the underlying superconducting state remains inconclusive. Further studies involving density of states measurements and spin-polarised transport in local/non-local Sr${}_2$RuO${}_4$ junctions with magnetic materials could lead to fundamental discoveries and a better understanding of the superconducting state.

超导 Sr2RuO4 结中的电子传输综述

我们回顾了 Sr 超导结中的电子输运${}_2$氧化钌${}_4$. 传输测量为手性畴壁提供了证据，因此，超导 Sr 中的手性超导性${}_2$氧化钌${}_4$，但到目前为止，潜在超导状态的对称性仍然没有定论。进一步研究涉及局域/非局域 Sr 中的态密度测量和自旋极化输运${}_2$氧化钌${}_4$ 与磁性材料的结可以导致基本发现和对超导状态的更好理解。
