Abstract

Measurements of magneto-tran sport on the organic superconductor
kappa-(BEDT-TTF)(2)I-3 in magnetic fields up to 23 T at 0.48 K under
hydrostatic pressures LIP to 9 kbar are reported. In this pronounced
two-dimensional (2D) electronic system strong anomalous damping effects
of Shubnikov-de Haas (SdH) oscillations are observed under very
specific experimental conditions. This hints to the presence of strong
electron correlations, which may Occur in 2D systems. SdH high pressure
experiments are reported, which show, that even 9 kbar cannot suppress
the above mentioned effects in kappa-(BEDT-TTF)(2)I-3.
