Abstract

Magnetooptical measurements have been performed on β″-(BEDT-TTF) (TCNQ) using the cavity perturbation techniques. β″-(BEDT-TTF)(TCNQ) has very exotic Fermi surface (FS). Several harmonic resonances were observed at various angles. We consider these resonances as q1D-periodic orbit resonance. The obtained Fermi velocity and the scattering time are 4.4×10 4m/s and 2.1×10-11s, respectively. When the magnetic field was rotated in the b*a-plane, the similar resonances are observed. According to these results, the FS topology of the system at low temperature is discussed.
