NMR evidence for very slow carrier density fluctuations in the organic metal (TMTSF)${}_2$ClO${}_4$

F. Zhang, Y. Kurosaki, J. Shinagawa +2

We have investigated the origin of the large increase in spin-echo decay rates for the ${}^{77}$Se nuclear spins at temperatures near to $T=30K$ in the organic superconductor (TMTSF)…
