Performing micromagnetic simulations, we study the efficiency of response of bulk and polycrystalline nickel oxide (NiO) to high-frequency (up to 100 GHz) magnetic fields with relevance to potential application of the antiferromagnet as a core materi

Spontaneous evolutions of domains in magnetic nanowires and of magnetic bubbles in open ferromagnetic nanolayers are investigated using micromagnetic simulations. We compare temperature dependent dynamics of domain wall (DW) systems in Permalloy (Py)

We study the effciency of the magnetoimpedance (MI) of thin-wall circumferentially ordered nanotubes in sub-GHz and GHz frequency regimes using micromagnetic simulations. We consider empty ferromagnetic tubes as well as tubes filled with non-magnetic

Magnetization of soft-ferromagnetic nano- and microtubes of nanometer-thin walls (a single-widening rolled-up nanomembranes) is theoretically studied using analytical and numerical approaches including different stress-induced anisotropies. Within th

We study the externally-driven motion of the domain walls (DWs)of the pi/2 type in (in-the-plane ordered) nanostripes of the crystalline cubic anisotropy. Such DWs are much narrower than the transverse and vortex pi DWs of the soft-magnetic nanostrip
