A Review of Electronic Transport in Superconducting Sr${}_2$RuO${}_4$ Junctions

Abstract

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.
