| Outline of Final Research Achievements |
Identification of the superconducting gap structure, which is closely related to the pairing interaction, is crucial to resolve the pairing mechanism of unconventional superconductivity. One of the powerful methods to determine the gap anisotropy is field-angle-resolved specific heat measurement. In this project, we have developed the apparatus to measure the field-angle-resolved specific heat under uniaxial pressure in order to uncover exotic features of heavy-fermion superconductivity. Furthermore, gap structures of various heavy-fermion superconductors have been investigated by this method at ambient pressure.
