The pressure dependence of the Fermi surface of K has been calculated using the Korringa–Kohn–Rostoker (KKR) method and local exchange potentials adjusted to simulate the effect of a nonlocal operator. Agreement with the experimental data is obtained. Some effective masses have also been calculated.

Abstract Magnetoresistance measurements of Copper and Silver single crystals in weak magnetic fields at 4.2 K are reported. In addition, the magnetosresistance has been calculated. The model used is based on ROAF's analytical representation of the Fermi surface. In view of the simplifying as­ sumptions made about bandstructure and scattering mechanism, the experimental data are found to agree reasonably well with the results of the numerical calculations.

The tunnel junctions between superconductors where the Fermi surface (FS) is partially dielectrized are considered. The dielectrization due to Coulomb- and (or) electron-phonon interactions leads to the emergence of the dielectric gap Σ on nested FS sections and the existence of the charge-density waves below temperature T=T d . When T<T c <T d the partially-dielectrized metals become superconductors with a corresponding gap ∆. The voltage dependences of the nonstationary Josephson current and quasiparticle current are calculated for such junctions. The current-voltage (I–V) characteristics involve several Riedel-type singularities and jumps for voltages equal to definite combinations of gaps ∆ and Σ in the fermion excitation spectrum. So, I–V curves are much more complex than the ones for usual BCS-type superconductors. The results for quasiparticle tunneling agree with the experimental data available for oxides.
