High-temperature dimensional crossover in the organic superconductor (TMTSF) 2ClO 4

Abstract

1H nuclear magnetic resonance and electrical resistance measurements were made for the organic superconductor (TMTSF) 2ClO 4 (tetramethyltetrafulvalenium-perchlorate). As a result, a high-temperature electronic dimensional crossover was unambiguously identified for the first time.
