The angular-dependent magnetoresistance of (Per)(2)[Au(mnt)(2)] under pressure has revealed geometrical effects associated with the crystallographic parameters. Pressure suppresses the charge-density wave ground state of the material and in the metallic state both geometrical and orbital quantum interference effects appear. Through magnetic field dependence and orientation, the orbital and geometrical effects are independently identified. We compare the results from (Per)(2)[Au(mnt)(2)] with previous studies of the well-known Bechgaard salts.
