Thermal conductivity in noncollinear magnets
Margherita Parodi, Sergey Artyukhin
Magnetic memory and logic devices, including prospective ones based on skyrmions, inevitably produce heat. Thus, controlling heat flow is essential for their performance. Here we s…
Finite temperature magnetic interactions from first principles
Ravi Kaushik, Ryota Ono, Sergey Artyukhin
Density functional theory has demonstrated remarkable predictive power in calculating magnetic properties at zero temperature. At finite temperatures, thermally excited phonons may…
Observation of relativistic domain wall motion in amorphous ferrimagnets
Pietro Diona, Luca Maranzana, Sergey Artyukhin +1
Domain walls in ferrimagnets and antiferromagnets behave as relativistic sine-Gordon solitons with the spin-wave group velocity setting the ultimate velocity of domain walls and sp…
Competition Between Multiferroic and Magnetic Soliton Lattice States in DyFeO
S. E. Nikitin, N. D. Andriushin, Ø. S. Fjellvåg +5
Simultaneous breaking of time reversal and inversion symmetries in multiferroics couples ferroelectricity to magnetism and is a source of unusual physical phenomena that can be use…
Entangled orbital, spin, and ferroelectric orders in -electron magnet CsO
Ryota Ono, Ravi Kaushik, Sergey Artyukhin +3
Alkali superoxides differ from conventional transition metal magnets, exhibit magnetism from partially occupied oxygen molecular -orbitals. Among them, CsO stands out for…
