Role of the cooling rate in the stability of the superconducting phase of (TMTSF)_2ClO_4

Abstract

The noncentrosymmetric ClO${}_4$ anions of the organic superconductor (TMTSF)${}_2$ClO${}_4$ order below 24K. The size of domains where the anions are ordered is substantially dependent on the cooling rate which is a key parameter for the stability of the low temperature electronic ground states. We study the effect of the cooling rate on the SC phase within a self consistent approach in the framework of the time dependent Ginzburg-Landau theory taking into account the superconducting fluctuations. We derive the superconducting transition temperature which is found to decrease with increasing cooling rate in agreement with recent experimental data.
