摘要：

The Anderson transition in three dimensions in a randomly varying magnetic flux is investigated in detail by means of the transfer-matrix method with high accuracy. Systems both with and without an additional random scalar potential are considered. We find a critical exponent of nu=1.45+/-0.09 with random scalar potential. Without it, nu is smaller bur increases with the system size and extrapolates within the error bars to a value close to the above. The present results support the conventional classification of universality classes due to symmetry. [S0163-1829(98)09219-4].
