Calculation of the electronic structure and related physical properties of platinum

The electronic band structure, density of states, and Fermi surface of Pt metal have been calculated using the relativistic-augmented-plane-wave method. The Fourier series representation of the a priori band structure has been found to yield a Fermi surface in good agreement with the de Haas-van Alphen results. The subband densities of states of platinum have been calculated with 0.25-mRy resolution using a tetrahedron scheme. The temperature dependences of the spin susceptibility, the electrical resistivity, the nuclear spin-lattice relaxation rate, and the electronic-specific-heat coefficient have been calculated in the constant-matrix-element approximation and have been found to be in reasonable agreement with the experimental results.
