| Zusammenfassung | The structure of the eigenstates of disordered 2-D systems of size M x M in strong perpendicular magnetic fields is investigated. A multifractal behaviour is found in the centres of the Landau bands, which is described in terms of the f(α(q)) vs. α(q) spectrum. The eigenstates ψE, M(r) and the equilibrium current density jE,M(r) show similar f(α(q)) spectra which supports the view of a universal one-parameter scaling behaviour. |
