Abstract
The anion-disorder and two-dimensionality effect for the superconducting and SDW phase of (TMTSF) 2 ClO 4 was investigated through static magnetization and resistance measurements for various cooling rates through the CIO -4 ClO -4 anion ordering temperature. In the slowly cooled phase, we find a strong dependence of the superconducting transition temperature on the a-axis residual resistivity ρa due to the suppression of anion ordering. This behavior supports models of non-s-wave pairing in (TMTSF) 2 X. In the rapidly quenched phase, the transition temperature of SDW shows a large increase in the magnetic field. This means that the SDW phase of quenched (TMTSF) 2 ClO 4 is strongly suppressed by the two-dimensionality of the system.
