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

P. A. Igoshev, V. Yu. Irkhin

Densities of states for simple (sc) and base-centered (bcc) cubic lattices with account of nearest and next-nearest neighbour hopping integrals $t$ and $t^{\prime }$ are investigated in det…
