Abstract

kappa-(BEDT-TTF)(2)I-3 is an electronically extreme two-dimensional (2d) organic metal with a superconducting transition at around 4K. In magnetic fields above 12T the effective mass, as obtained from the temperature dependence of the amplitudes of Shubnikov-de Haas (SdH) oscillations, is magnetic field dependent as long as the magnetic field is arranged perpendicular to the conducting planes. In contrast to this byturning the magnetic field 27 degrees or even only by 9 degrees the observed effective mass (as obtained from SdH- and de Haas-van Alphen (dHvA)-measurements) is field independent. We suppose that the occurrence of anyons at temperatures below IK and in fields above 12T is the reason for the observed field dependence of the effective mass.
