Abstract
We have measured angle-dependent magnetoresistance oscillations and the int erplane millimetre-wave conductivity of the organic superconductor beta "-( ET)(2)SF5CH2CF2SO3 as a function of the orientation of the applied magnetic field. We observe harmonics of the cyclotron frequency in the real-space v elocity of quasiparticles orbiting the Fermi surface (FS). The harmonic amp litudes depend on the field orientation, providing a new way to measure the quasi-two-dimensional FS topology.
