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…
Regularities and features in the behavior of electrical and magnetic properties of CoFeZ (Z = Al, Si, Ga, Ge, Sn, Sb) half-metallic ferromagnetic Heusler alloys
Yu. A. Perevozchikova, V. Yu. Irkhin, A. A. Semiannikova +1
The electrical resistivity, magnetization, and Hall effect in CoFeZ (Z = Al, Si, Ga, Ge, Sn, Sb) ferromagnetic Heusler alloys are studied. A number of correlations between the…
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…
Rattling Phonon Modes in Quadruple Perovskites
Z. V. Pchelkina, E. V. Komleva, V. Yu. Irkhin +2
Rattling phonon modes are known to be origin of various anomalous physical properties such as superconductivity, suppression of thermal conductivity, enhancement of specific heat e…
