The detection of the fractional Landau level filling factor a?= 1/2 and low integer filling factors in the two-dimensional multilayer organic metal a-(BED-TTF)2I3 is presented, which shows the occurrence of electron localisation and electron-electron correlation in this bulk metallic two-dimensional system. These effects are found in the normal conducting state of the organic superconductor a-(BEDT-TTF)2I3. In addition, quantum oscillation measurements are found to be a very promising tool for direct detection of the chemical potential and its variation with magnetic field, even under rather complex fermiological conditions.
