摘要：

The Fermi surface topology and electronic bandwidth of the first ever organic superconductor containing magnetic ions, the charge transfer salt beta''-(BEDT-TTF)(4)[(H2O)Fe(C2O4)(3)].[6H5CN, have been studied using angle-dependent magnetoresistance oscillation (AMRO) and infrared (IR) reflectivity measurements. This material has a superconducting transition temperature of 7 It. AMRO data have been recorded at 1.4 K in a field of 15 T for all possible orientations of the sample with respect to the applied field. Several features with very strong azimuthal dependence are observed. The IR reflectivity is also very anisotropic; the reflectivity for E parallel to the needle axis is eight times greater than for the perpendicular direction. The results are discussed in relation to the calculated band structure and Fermi surface.
