Fingerprint of vortex-like flux closure in isotropic Nd-Fe-B bulk magnet
Mathias Bersweiler, Yojiro Oba, Evelyn Pratami Sinaga +5
Taking advantage of recent progress in neutron instrumentation and in the understanding of magnetic-field-dependent small-angle neutron scattering, here, we study the three-dimensi…
On the angular anisotropy of the randomly-averaged magnetic neutron scattering cross section of nanoparticles
Michael P. Adams, Evelyn Pratami-Sinaga, Andreas Michels
We calculate the magnetic SANS cross section of dilute ensembles of uniformly magnetized and randomly-oriented Stoner-Wohlfarth particles using the Landau-Lifshitz equation. The fo…
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…
Micromagnetic simulation of neutron scattering from spherical nanoparticles: Effect of pore-type defects
Evelyn Pratami Sinaga, Michael P. Adams, Mathias Bersweiler +6
We employ micromagnetic simulations to model the effect of pore-type microstructural defects on the magnetic small-angle neutron scattering cross section and the related pair-dista…
Magnetic neutron scattering from spherical nanoparticles with Neel surface anisotropy: Atomistic simulations
Michael P. Adams, Andreas Michels, Hamid Kachkachi
We consider a dilute ensemble of randomly-oriented noninteracting spherical nanomagnets and investigate its magnetization structure and ensuing neutron-scattering response by numer…
Magnetic neutron scattering from spherical nanoparticles with Neel surface anisotropy: Analytical treatment
Michael P. Adams, Andreas Michels, Hamid Kachkachi
The magnetization profile and the related magnetic small-angle neutron scattering cross section of a single spherical nanoparticle with Neel surface anisotropy is analytically inve…
