Itinerant electron metamagnetism for lattices with van Hove density-of-states singularities near the Fermi level
F. A. Vasilevskiy, P. A. Igoshev, V. Yu. Irkhin
Itinerant-electron metamagnetism is investigated within the Hubbard model for various lattices having van Hove singularities (vHS) in the electronic spectrum: face-centered cubic a…
Spin-orbit coupling induced orbital entanglement in a three-band Hubbard model
Petr A. Igoshev, Danil E. Chizhov, Valentin Yu. Irkhin +1
The effect of the spin-orbit coupling on the ground state properties of the square-lattice three-band Hubbard model with a single electron per site is studied by a generalized Hart…
Inverse magnetocaloric effect and phase separation induced by giant van Hove singularity in itinerant ferromagnetic metal
Petr A. Igoshev, Igor A. Nekrasov
A thermodynamic theory based on Landau grand potential expansion for ferromagnetic-paramagnetic phase transitions is developed for an electronic phase-separated state. It is rigoro…
