Abstract

The authors calculate the scaling behaviour of the magneto-resistance of a regular three-dimensional (3D) fractal network model in a weak magnetic field. The method used is a discretised version of a previously described continuum theory. Exponents are calculated that characterise the power-law dependence of both the transverse and the longitudinal magneto-resistance on the total size. Results are compared with a previously published prediction of scaling theory for the magneto-resistance near the percolation threshold.
