摘要：

The density of states, and the mobility edge are calculated numerically for a new model of a three-dimensional disordered system in the presence of a quantizing magnetic field. The critical exponent of the disorder induced metal-insulator transition is found to be nu = 1.3 +/- 0.2 close to the value reported previously for the Anderson model without magnetic field.
