1. Basic Physical Properties of the High-Tc Superconductors

2. Search for the New Superconductors

3. Search for the New High Thermal Conducting Materials due to Spins

Since the discovery of high-temperature superconductors with the critical temperature Tc over the liquid nitrogen temperature (77 K), twenty years have passed. However, the mechanism of the high-temperature superconductivity has not yet been clarified. In our laboratory, the following has been investigated on the high-temperature superconductors and the related materials, in order to elucidate the mechanism of the high-temperature superconductivity; preparation of the high-quality samples including large-scale single-crystals, structural analysis, basic physical properties, viz., electrical, magnetic, thermal properties and so on. On the other hand, search for new superconductors has also been carried out aiming at the discovery of a room-temperature superconductor after all. For that purpose, new synthetic techniques have also been developed such as a low-temperature synthetic technique, a soft-chemical technique and a microwave synthetic technique. Thermal conductivity due to spins in the low-dimensional quantum spin systems have been studied from both viewpoints of the search for new high thermal conducting materilas and the fundamental physics.
