The motion of domain walls in GdFeCo-type ferrimagnets near the point of compensation of sublattice spins s1 and s2, when the effects of the exchange increase in the limiting wall velocity take place, is theoretically studied. The energy E and moment

Recently it was shown that ferrimagnetic nanodisks support a magnetic vortex state that can oscillate at frequencies up to 30 GHz, suggesting that a ferrimagnetic free layer in a spin-torque-driven nanopillar oscillator would have a significantly hig

A spin-polarized current in a nanocontact has been shown to induce the formation of a magnetic vortex at the nanocontact by the Oersted field, and spin-torque drives the vortex core in an elliptical orbit about the nanocontact. For the case of an ext

Static magnetic solitons in a thin film such as skyrmions are metastable states that can be stabilized through a balance of the exchange interaction and various relativistic interactions. One of the most effective stabilizing terms is the antisymmetr

The dynamics of a magnetic vortex in a thin magnetically soft ferromagnetic disc with a submicron diameter has been analyzed. Under the action of field pulses with a duration of the order of 10–100 ps, the vortex undergoes a complex motion. The ana

Submicron permalloy rings can have a vortex ground state as a result of the competing effects arising from the exchange and magnetostatic interactions. The dynamic properties of this state are investigated by analytical calculations of the structure

Both static and dynamic properties of the magnetic dot array with the uniform in-plane magnetization with the most symmetric configuration (round dots placed in a square lattice) have been investigated. Due to the long distance dipole coupling physic

Stable magnetic vortex-antivortex-vortex structures can form on a thin ferromagnetic disk at two separated nanocontacts with the vortices at the nanocontacts and the antivortex between the nanocontacts. When the vortices are pinned to the nanocontact
