Angular magnetoresistance study of the organic superconductor (TMTSF)(2)ReO4

We have studied the angle dependent magnetoresistance of the title compound when the magnetic field rotates in the be plane. Lebed-type resonance is c learly observed both in R-zz and R-xx. The most remarkable finding is that the resonance effects take place only at the angles corresponding to p/g = odd integers. Also found are additional fast oscillatory parts superposed o n the Lebed oscillations, which are clearer in R-zz than in R-xx. Pressure dependence and the effect of mixed anion orderings are investigated.
