Abstract
Full single-phonon contribution to the tensor of the electronic d.c. hopping conductivity in external magnetic fieldℋ is found and its first derivative (with respect toℋ) is shown to vanish atℋ=0. Thus the Hall mobilityμ H is found to be proportional to the squared electron-phonon coupling constantg 2 at least, in accordance with extremely low values ofμ H in amorphous semi-conductors and glasses.
