Polarized neutron scattering as a probe for vortex-type spin correlations in iron oxide multicore assemblies

Venus Rai, Ivan Titov, Elizabeth M. Jefremovas +11

We report an experimental investigation of the magnetic microstructure of iron oxide multicore assemblies by means of polarized small-angle neutron scattering (SANS). Guided by a r…

Spin-disorder-induced angular anisotropy in polarized magnetic neutron scattering

I. Titov, M. Bersweiler, M. P. Adams +14

We experimentally report a hitherto unseen angular anisotropy in the polarized small-angle neutron scattering (SANS) cross section of a magnetically strongly inhomogeneous material…

Scaling in Magnetic Neutron Scattering

Venus Rai, Andreas Michels

We report the discovery of scaling in the mesoscale magnetic microstructure of bulk ferromagnets. Supported by analytical micromagnetic theory, we introduce the field-dependent sca…

Quantum and classical magnetic Bloch points

Vladyslav M. Kuchkin, Andreas Haller, Štefan Liščák +5

A Bloch point represents a three-dimensional hedgehog singularity of a magnetic vector field in which the magnetization vanishes. However, standard micromagnetic theory, developed…

Magnetic microstructure of nanocrystalline Fe-Nb-B alloys as seen by small-angle neutron and X-ray scattering

Venus Rai, Ivan Titov, Michael P. Adams +3

We have investigated the magnetic microstructure of two-phase Fe-Nb-B~based Nanoperm alloys using unpolarized small-angle neutron scattering (SANS) and small-angle X-ray scattering…
