Dimensional crossovers in magnetoresistance oscillations in the quasi-one-dimensional compounds (TMTSF)2ClO4 and (DMET)2I3. - 155 p.

We report angle-dependent magnetoresistance oscillations in strong static (33 T) and pulsed (45 T) magnetic fields oriented in and near the most conducting plane, with small field component along the least conducting interlayer direction, in the quasi-1 dimensional (Q1D) compounds (TMTSF)2ClO4 and (DMET)2I3. A hybrid plastic-metal cryoprobe system with pseudo-dual-axis rotation has been built for the pulsed field measurements. We observe rich magnetoresistance oscillations, interpreted as resulting from an interference effect of commensurate electron trajectories in the extended Brillouin zone. This is known as the Lee-Naughton-Lebed (LNL) effect. We have found that the field-dependent magnetoresistance shows crossovers between 1-dimensional (1D) and 2-dimensional (2D) behavior at local resistance maxima and minima (versus field angle), respectively. The interference commensurate (IC) theory is consistent with these experiments, such that the LNL effect persists to the highest measured fields.
