| Outline of Final Research Achievements |
This study was carried out to reveal the electronic state of the quasi-one-dimensional organic superconductor (DME)2I3, which conducts electricity only along one direction of its crystal very well, in its superconducting state below 0.5 K. We have developed a new system to measure thermal conductivity of small (~1 mm) and fragile crystal. Temperature dependence of its thermal conductivity was successfully determined. Thermoelectric power was also measured under pressure. We determined how free electrons change their motion under pressure by combining the present results and the previous magnetoresistance study.
