The effect of disorder on confined metallic cavities with an Aharonov-Bohm flux line is addressed. We find that, even deep in the diffusive regime, large values of persistent currents may arise for a wide variety of geometries. We present numerical results supporting an anomalous scaling law of the average typical current $〈{I}_{\mathrm{typ}}〉$ with the strength of disorder w, $〈{I}_{\mathrm{typ}}〉\ensuremath{\sim}{w}^{\ensuremath{-}\ensuremath{\gamma}}$ with $\ensuremath{\gamma}l2.$ This is…
