| Research Abstract |
The molecular conductor (TMTSF)_2X has been actively studied for more than 30 years as an archetypal quasi-one-dimensional conductor, in which conductivity differs for all three principle directions. We succeeded in measuring the heat capacity of single-crystalline (TMTSF)_2ClO_4 with accurately controlling the field direction. From the obtained results, we revealed the superconducting gap structure and the thermodynamic phase diagram. These are fundamentally important information for understandings of superconductivity of the TMTSF family but have not been experimentally clarified for this 30 years.
