Magnetoresistance study of low-dimensional electrons in the Bechgaard salts

High magnetic field in addition to low temperature and high pressure plays an important role in the study of transport properties of low-dimensional electron systems found in organic conductors, especially those in the Bechgaard salts. Magnetoresistance as a function of field direction as well as magnetic field strength shows magnetic oscillations, resonant behaviors, and quantum effects. Comparison of these properties among various Bechgaard salts is particularly informative because anions impose many different kinds of weak periodic potential to the energy spectrum when they undergo structural orderings.
