Problem
A hypothetical face-centred cubic metal has lattice constant a=3.60A˚ and three valence electrons per atom, split across its bands exactly as aluminium's are: the first band completely full, the second holding 0.90 electrons per atom and the third 0.10 (out of two places per atom in each). Predict the sign of the strong-field Hall coefficient and find its size.
