Abstract

We report the existence of rapid magnetic quantum oscillations in the low-temperature metallic phase of the organic conductor bis- tetramethyltetraselenafulvalene perchlorate, (TMTSF)2ClO4, at magnetic fields lower than those associated with observed spin-density-wave (SDW) transitions. These resistance oscillations are seen at low field only for samples cooled extremely slowly through an anion at 24 K, and become more pronounced at fields greater than 10 T. Their frequency remains unchanged from 4 to 30 T, through the magnetic-field-induced SDW transitions which occur from 5 to 8 T (at T=1 K). Angular studies reveal a two-dimensional nature. These results suggest an intrinsic magnetic periodicity which is unaffected by the SDW transitions, and require a new mechanism for their explanation.
