抄録

The Ginzburg-Landau coherence lengths are determined from the temperature dependence of the magnetization by fitting measured results with the renormalization theory of the fluctuation developed for layered superconductors. The derived interlayer coherence lengths are 6±2 Å and 3.2±0.5 Å for κ-(BEDT–TTF)₂Cu[N(CN)₂]Br and κ-(BEDT–TTF)₂Cu(NCS)₂, respectively, which are remarkably shorter than the interlayer spacing. It is also found that these coherence lengths are virtually unaffected by isotope substitution in BEDT–TTF molecules.
