Magnetic-field-induced chiral stability of interface superconductivity in Sr2RuO4/Ru
We show the magnetic-field-induced chiral transition from the non-chiral state near the onset of the 3K-phase in the eutectic Sr2RuO4-Ru. The magnetic field along the c-axis stabilizes the chiral state in the 3K-phase which localizes near an interface in contact with a Ru-metal inclusion. In experim...

| Summary: | We show the magnetic-field-induced chiral transition from the non-chiral state near the onset of the 3K-phase in the eutectic Sr2RuO4-Ru. The magnetic field along the c-axis stabilizes the chiral state in the 3K-phase which localizes near an interface in contact with a Ru-metal inclusion. In experiment the distinct behavior of the chiral stability for the two field directions have been observed in agreement with our theoretical picture. Therefore, this finding is a good evidence for chiral superconductivity in Sr2RuO4. These chiral features found for the channels, such as px+ipy and dxz+idyz. We also present the change of chirality generated by the paramagnetic current. Oxide Superspin Workshop 2019, OSS2019 |
