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 and are investigated in det…
Investigation of magnetocaloric effect: Stoner approximation vs DMFT
P. A. Igoshev, I. A. Nekrasov, N. S. Pavlov +2
A comparative study of the magnetocaloric effect (MCE) in metals within the single-band Hubbard model on the face-centered cubic (fcc) lattice using both mean-field (Stoner) approx…
Spiral magnetism in the single-band Hubbard model: the Hartree-Fock and slave-boson approaches
P. A. Igoshev, M. A. Timirgazin, V. F. Gilmutdinov +2
The ground-state magnetic phase diagram is investigated within the single-band Hubbard model for square and different cubic lattices. The results of employing the generalized non-c…
Magnetic fluctuations and itinerant ferromagnetism in two-dimensional systems with van Hove singularities
P. A. Igoshev, A. A. Katanin, V. Yu. Irkhin
We use the quasistatic approach to analyze the criterion of ferromagnetism for two-dimensional (2D) systems with the Fermi level near Van Hove singularities (VHS) of the electronic…
