Abstract
An analysis of recent experiments on aluminium shows that in a high magnetic field the resistivity has a temperature dependence proportional to T3, similar in form and magnitude to that of an impure sample in zero field, and markedly different from the T5 behaviour of pure material in zero field. The idea of momentum nonconservation at electron-phonon collisions, which was introduced to explain the impurity effect, is extended to account for the temperature dependent part of the magnetoresistance.
