Giant Van Hove Density of States Singularities and Anomalies of Electron and Magnetic Properties in Cubic Lattices

Densities of states for simple (sc) and base-centered (bcc) cubic lattices with account of nearest and next-nearest neighbour hopping integrals t and t ' are investigated in detail. It is shown that at values of τ ≡ t '/ t = τ*, corresponding to the change in isoenergetic surface topology,...
