While the magnetic field dependence of the classical Hall law presents no anomaly at high temperatures, we find a breakdown of the Drude-Lorentz law for the longitudinal conductance beyond a crossover magnetic field B_c ~ 1 T, which turns out to be correlated with the onset of the integer quantum Hall effect at low temperatures. We show that the high magnetic field regime at B > B_c can be understood","authors_text":"B. A. Piot, C. L. Campbell, D. K. Maude, M. Fl\\\"oser, M. Henini, R. Airey, S. Florens, T. Champel, Z. R.
