Magnetic-field–induced transition and quantum oscillations in tetramethyltetraselenafulvalenium perrhenate, (TMTSF)2ReO4

Abstract

We report magnetoresistance measurements in (TMTSF)2ReO4 which give evidence for a magnetic-field–induced transition. We also find Shubnikov–de Haas oscillations above and below the field-induced transition-a result not explained by recent theories of this novel transition.
