Deterministic control of antiferromagnetic domain walls by circular phonons
Vladislav Bilyk, Nikolai Khokhlov, Viktoriia Radovskaia +12
In an antiferromagnet, areas with different orientations of the antiferromagnetic Néel vector, which plays the role of the order parameter, can coexist, thus forming antiferromagne…
Exchange striction determines how fast antiferromagnetic insulators demagnetize
Aleksandr Buzdakov, Ravi Kaushik, Nikolai Khokhlov +2
Antiferromagnets combine terahertz spin dynamics with insensitivity to stray fields, and how quickly their order can be manipulated sets the speed limit on device operation. Femtos…
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…
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…
