Outline of Final Research Achievements

To clarify the topological quantum phenomena, especially novel surface/interface phenomena, in superconductors with broken time-reversal symmetry, we investigated ruthenate superconductor Sr2RuO4 and its eutectic, as well as hybrid systems consisting of a conventional superconductor and a ferromagnet.
We discovered the half-quantum flux state in micro-rings of Sr2RuO4, and in-gap density of states indicating its chiral-edge mode. We also accumulated new facts concerning its superconducting symmetry, such as reconfirming evidence for spin-triplet pairing from NMR and the first-order superconducting transition under in-plane magnetic fields. We deepened our knowledge of the odd-frequency pairing state characteristic of topological superconductivity. We developed a hybrid system of ferromagnetic thin film of SrRuO3 deposited on the Sr2RuO4 crystal surface, which is ideal for the investigation of novel proximity effects involving odd-frequency pairing.
