Abstract

Magneto-optical measurements of a quasi-one-dimensional (q1D) organic superconductor (DMET)2I3 have been performed by using a cavity perturbation technique. Several resonant absorption lines, which can be attributed to the q1D periodic orbit resonance (q1D POR), were observed as well as quite unusual high order q1D PORs coming from its corrugated Fermi surface (FS) in the interlayer direction. Moreover, these resonances seem to disappear when the magnetic field is applied close to the conducting axis due to the FS topological effect, and the transfer integral ratio can be obtained from the angular dependence of q1D POR. The FS of (DMET)2I3 can be estimated from these analyses of q1D PORs, and we will show that it has a characteristic FS structure. The observed results also indicate that the interlayer transport of (DMET)2I3 is coherent.
