Unusual half-metallic state in unconventional magnets
Yuri B. Kudasov
Half-metallic ferromagnets exhibit a gap in the density of states for one spin projection while remaining gapless for the opposite spin. We show that in helimagnets an unusual half…
Topological bands in metals
Yu. B. Kudasov
In crystalline systems with a superstructure, the electron dispersion can form a nontrivial covering of the Brillouin zone. It is proved that the number of sheets in this covering…
Topological metal state in helimagnets
Yu. B. Kudasov
A theory for nontrivial topology of band structure in metallic helimagnets is developed. Two theorems on electron dispersion in helimagnets are proved. They reveal a Kramers-like d…
Electrons in helical magnetic field: a new class of topological metals
Yu. B. Kudasov
Two theorems on electron states in helimagnets are proved. They reveal a Kramers-like degeneracy in helical magnetic field. Since a commensurate helical magnetic system is transiti…
On semiconductor--metal transition in FeSi induced by ultrahigh magnetic field
Yuri Kudasov, Dmitrij Maslov
At low temperatures, iron monosilicide is a strongly correlated narrow-gap semiconductor. A first order transition to metal state induced by magnetic field was observed for the fir…
Giant widening of interface magnetic layer in almost compensated iron garnet
Y. B. Kudasov, M. V. Logunov, R. V. Kozabaranov +9
A two-sublattice ferrimagnet undergoes a transition from a collinear to canted magnetic phase at magnetic field oriented along an easy magnetization direction. In this work, we stu…
