Diamagnetic Susceptibility of Metals with Complicated Crystal Structures

Abstract
We have derived an expression for the diamagnetic susceptibility of metals with complicated crystal structures from the general expression for the diamagnetic susceptibility obtained by Misra and Roth in a pseudopotential formalism. We have used this expression to calculate the diamagnetic susceptibility of zinc, and our result agrees well with the experimental result calculated from the available data. We have also used the known parameters of bismuth to study the variation of susceptibility with the Fermi level. Our results indicate that if there were a gap over most of the original Fermi surface, we expect to have positive diamagnetism.
