Vortex ground state for small arrays of magnetic particles with dipole coupling
S. A. Dzian, A. Yu. Galkin, B. A. Ivanov +2
We show that a magnetic vortex is the ground state of an array of magnetic particles shaped as a hexagonal fragment of a triangular lattice, even for an small number of particles i…
Core-Core Dynamics in Spin Vortex Pairs
S. S. Cherepov, B. C. Koop, V. Korenivski +4
We investigate magnetic nano-pillars, in which two thin ferromagnetic nanoparticles are separated by a nanometer thin nonmagnetic spacer and can be set into stable spin vortex-pair…
Magnetic vortex as a ground state for micron-scale antiferromagnetic samples
E. G. Galkina, A. Yu. Galkin, B. A. Ivanov +1
Here we consider micron-sized samples with any axisymmetric body shape and made with a canted antiferromagnet, like hematite or iron borate. We find that its ground state can be a…
Collective modes for an array of magnetic dots with perpendicular magnetization
P. V. Bondarenko, A. Yu. Galkin, B. A. Ivanov +1
The dispersion relations of collective oscillations of the magnetic moment of magnetic dots arranged in square-planar arrays and having magnetic moments perpendicular to the array…
Magnetic vortex as a ground state for sub-micron antiferromagnetic particles
A. Yu. Galkin, B. A. Ivanov
For submicron particles shaped as any axisymmetric body and made with standard canted antiferromagnet like hematite or iron borate, the ground state may comprise of a magnetic vort…
Solitons in isotropic antiferromagnets: beyond a sigma model
E. G. Galkina, A. Yu. Galkin, B. A. Ivanov
Isotropic antiferromagnets shows a reach variety of magnetic solitons with non-trivial static and dynamic properties. One-dimensional soliton elementary excitations have a periodic…
