11.1 Due to its spin, the electron possesses a magnetic moment μB.

Treating the conduction electrons in a metal as a free electron gas, obtain an expression (involving integrals over Fermi–Dirac distribution functions) for the magnetization due to the magnetic moments of the conduction electrons, when placed in a magnetic field. Evaluate this expression at the absolute zero of temperature.
