NMR observation of a high temperature phase transition in the organic superconductor (TMTSF)2ClO4

Abstract

A high temperature phase transitional behavior in the organic superconductor (TMTSF)2ClO4 (tetramethyltetrafulvalenium-perchlorate) was manifest in our 1H NMR measurements. Our observations are discussed in the light of a dimensional crossover of the electronic transport. © 2002 Elsevier Science B.V. All rights reserved.
