Generic role of the Dzyaloshinskii-Moriya interaction in nanocrystalline ferromagnets

S. Erokhin, D. Berkov, A. Michels

Motivated by recent experimental polarized neutron results, we present a numerical micromagnetic study of the interfacial (intergrain) Dzyaloshinskii-Moriya interaction (DMI) in na…

Optimal control of magnetization reversal in a monodomain particle by means of applied magnetic field

G. J. Kwiatkowski, M. H. A. Badarneh, D. V. Berkov +1

A complete analytical solution to the optimal reversal of a macrospin with easy-axis anisotropy is presented. Optimal control path minimizing the energy cost of the reversal is ide…

Resolving complex spin textures in nanoparticles by magnetic neutron scattering

Laura G. Vivas, Rocio Yanes, Dmitry Berkov +5

In the quest to image the three-dimensional magnetization structure we show that the technique of magnetic small-angle neutron scattering (SANS) is highly sensitive to the details…

Dipolar spin-misalignment correlations in inhomogeneous magnets: comparison between neutron scattering and micromagnetic approaches

Sergey Erokhin, Dmitry Berkov, Andreas Michels

In inhomogeneous bulk ferromagnets, the dominating sources of spin disorder are related to spatial variations of (i) the magnitude of the local saturation magnetization and of (ii)…

Comment on "Origin of Surface Canting within Nanoparticles"

Andreas Michels, Dirk Honecker, Sergey Erokhin +1

We comment on the Letter "Origin of surface canting within nanoparticles" by K.L. Krycka et al. [Phys. Rev. Lett. , 147203 (2014)].
