Abstract

The quasi-two-dimensional organic superconductor beta "-(BEDT-TTF)(2)SF5CH2CF2SO3 (T-c approximate to 4.4 K) shows very strong Shubnikov-de Haas (SdH) oscillations which are superimposed on a highly anomalous steady background magnetoresistance, Rb. Comparison with de Haas-van Alphen oscillations allows a reliable estimate of Rb which is crucial for the correct extractionof the SdH signal. At low temperatures and high magnetic fields insulatingbehavior evolves. The magnetoresistance data violate Kohler's rule, i.e., cannot be described within the framework of semiclassical transport theory,but converge onto a universal curve appropriate for dynamical scaling at ametal-insulator transition.
