Magnetic-fieldinduced transition and quantum oscillations in tetramethyltetraselenafulvalenium perrhenate, (TMTSF)2ReO4

We report magnetoresistance measurements in (TMTSF)2ReO4 which give evidence for a magnetic-field induced transition. We also find Shubnikovde Haas oscillations above and below the field-induced transitiona result not explained by recent theories of this novel transition. © 1986 The American Physical Society.
