Outline of Final Research Achievements |
The purpose of this project is twofold; the search for quantum critical phase and Bose condensation (such as superconductivity) in quasicrystal. For the former purpose, we obtained a result suggesting the existence of the quantum critical phase in quasicrystal via the investigation of high-pressure magnetic properties of the relevant approximant crystal. For the latter purpose, we succeeded in finding new approximant superconductors with the Tsai-type cluster, but failed to find a new superconducting quasicrystal. We also found that while the superconductivity occurs in the Al-Mg-Zn approximants, it does not in the quasicrystal. To resolve this origin remains to be resolved in the future.
