Abstract The profile, radius, and energy of chiral skyrmions, found in magnetic materials with the Dzyaloshinskii–Moriya (DM) interaction easy-axis anisotropy perpendicular to film, have been previously calculated asymptotic limits small large skyrmion as functions model parameter. We extend analysis case an external field or a combination field. formulae for radius are then modified, by use fi...

In this paper, we study the thin-film limit of micromagnetic energy functional in presence bulk Dzyaloshinskii–Moriya interaction (DMI). Our analysis includes both a stationary [Formula: see text]-convergence result for energy, as well identification asymptotic behavior associated Landau–Lifshitz–Gilbert equation. particular, prove that, limiting model, part DMI term behaves like projection mag...

The purpose of this work is to study the influence four-magnon (4M) parametric instability on spin pumping by dipole-exchange magnetostatic surface waves (MSSW) with help inverse Hall effect (ISHE) in structures based yttrium-iron garnet (YIG) and platinum (Pt). Methods. experiments were carried out using delay line YIG(900 nm)/Pt(9 nm) where electromotive force (EMF) induced ISHE demonstrates ...

The influence of spin waves on rapid rotational magnetization reversal (switching) in a thin ferromagnetic film is investigated by means of a semiclassical, continuum theory which includes external, anisotropy, exchange, and magnetostatic (dipolar) fields. To simplify the magnetostatic field, a "thin-film approximation" is introduced, in which the magnetization is replaced by its average over t...

It is shown that a term in the form of Dzyaloshinskii-Moriya interaction (DMI) contributes to free energy ferromagnetic (FM) film on paramagnetic (PM) (an FM above critical temperature ${T}_{c}$) or superconducting (SC) substrate occurring London limit. This contribution results from magnetostatic between and under which magnetization induces PM supercurrent SC interacts with their stray fields...

We describe techniques for creating long-lived magneto-optical and magnetostatic traps for neutral atoms. These traps exist in a sealed cryogenic environment with a temperature near 4 K, where the background gas pressure can be extremely low. To date we have observed cesium magneto-optical traps with background-limited lifetimes in excess of 1 h, and magnetostatic traps with lifetimes of nearly...

We investigate the competing effects of interlayer exchange coupling and magnetostatic coupling in the magnetic heterostructure ([Co/Pt]/NiO/[Co/Pt]) with perpendicular magnetic anisotropy (PMA). This particular heterostructure is unique among coupled materials with PMA in directly exhibiting both ferromagnetic and antiferromagnetic coupling, oscillating between the two as a function of spacer ...
