| Outline of Final Research Achievements |
Iron-based superconductors are known to have multi components. Nontrivial phase differences among components appear in a three-component superconductor when the inter-component interactions are repulsive, and a time-reversal-symmetry-broken state is stablized even without external magnetic field. We have revealed that, (1) the critical current is direction dependent in a Josephson junction between the TRSB superconductor and a single-component one; (2) steps with un-quantized flux appear in the magnetization curve (B-H curve) of a TRSB superconductor, and steps appear always in pair with the sum of fluxes equal to the flux quantization.
