Pauli spin paramagnetism and electronic specific heat in generalised d-dimensions

The temperature variations of Pauli spin paramagnetic susceptibility and the electronic specific heat of solids, are calculated as functions of temperature following the free electron approximation, in generalised d-dimensions. The results are compared and become consistent with that obtained in three dimensions. Interestingly, the Pauli spin paramagnetic susceptibility becomes independent of temperature only in two dimensions.
