| Outline of Final Research Achievements |
We have developed new local magnetic field measurement system using SQUIDs (Al tunnel junction, Nb weak link, and FIB-CVD W type) in this study. We have tried to observe the chiral edge currents, using this system, to prove experimentally that Sr2RuO4 is a chiral P wave spin triplet superconductor.
However, chiral edge currents, etc., phenomenons that show clearly chiral superconductivity has not been observed.
