| Outline of Final Research Achievements |
One of the main purposes of this study is to determine the gap structure in non-trivial superconductors, which exhibit unconventional physical properties unseen in conventional superconductors. This study is important in uncovering the pairing mechanism in such materials, which may ultimately lead to novel superconductor with high transition temperature. In this study we take up several unconventional superconductors in order to determine their gap structures. In some of them the gap structures are unambiguously determined by using field rotation specific heat measurement, but there remain undetermined due to sample quality. Namely the heavy Fermion superconductor UTe2, which is one of the focus in condensed matter community and claimed to be a point node gap structure by us must be rechecked by using ultra-high quality samples with Tc=2K. This is an urgent next work.
