The inhomogeneous 3-Kelvin (3K) phase of the eutectic Sr₂RuO₄ with Ru inclusions nucleates superconductivity at the interface between Ru and Sr₂RuO₄. The structure of the interface state and its physical properties are examined here. Two superconducting phases are identified between the transitions to the bulk phase at 1.5 K and to the 3K phase. The nucleation of the 3K phase results in a...
