Instability in domain wall dynamics in almost compensated ferrimagnets
R. V. Ovcharov, B. A. Ivanov, E. G. Galkina +2
Nanoscale self-localized topological spin textures, such as domain walls and skyrmions, are of interest for the fundamental physics of magnets and spintronics applications. Ferrima…
Resonant pinning spectroscopy with spin-vortex pairs
E. Holmgren, A. Bondarenko, B. A. Ivanov +1
Vortex pairs in magnetic nanopillars with strongly coupled cores and pinning of one of the cores by a morphological defect, are used to perform resonant pinning spectroscopy, in wh…
Static and dynamic properties of vortex pairs in asymmetric nanomagnets
B. C. Koop, M. Gruschke, T. Descamps +3
Stacked spin-vortex pairs in magnetic multilayered nanopillars, with vertical separation between the vortices small compared to the vortex core size, exhibit spin dynamics absent 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…
Spin nematic state for a spin S=3/2 isotropic non-Heisenberg magnet
Yu. A. Fridman, O. A. Kosmachev, B. A. Ivanov
system with general isotropic nearest-neighbor exchange within a mean-field approximation possesses a magnetically ordered ferromagnetic state and antiferromagnetic state,…
Large temperature dependence of the Casimir force at the metal-insulator transition
E. G. Galkina, B. A. Ivanov, Sergey E. Savel'ev +2
The dependence of the Casimir force on material properties is important for both future applications and to gain further insight on its fundamental aspects. Here we derive a genera…
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…
