Configuration of the magnetosome chain: a natural magnetic nanoarchitecture
I. Orue, L. Marcano, P. Bender +10
Magnetospirillum gryphiswaldense is a microorganism with the ability to biomineralize magnetite nanoparticles, called magnetosomes, and arrange them into a chain that behaves like…
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…
Revealing defect-induced spin disorder in nanocrystalline Ni
Mathias Bersweiler, Evelyn Pratami Sinaga, Inma Peral +7
We combine magnetometry and magnetic small-angle neutron scattering to study the influence of the microstructure on the macroscopic magnetic properties of a nanocrystalline Ni bulk…
The benefits of a Bayesian analysis for the characterization of magnetic nanoparticles
Mathias Bersweiler, Helena Gavilan Rubio, Dirk Honecker +2
Magnetic nanoparticles offer a unique potential for various biomedical applications, but prior to commercial usage a standardized characterization of their structural and magnetic…
Magnetic correlations in polycrystalline
Mathias Bersweiler, Philipp Bender, Inma Peral +5
We investigated a polycrystalline sample of the ferrimagnetic compound by magnetometry and small-angle neutron scattering (SANS). The magnetization cu…
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…
Unraveling Nanostructured Spin Textures in Bulk Magnets
Philipp Bender, Jonathan Leliaert, Mathias Bersweiler +2
One of the key challenges in magnetism remains the determination of the nanoscopic magnetization profile within the volume of thick samples, such as permanent ferromagnets. Thanks…

We report the results of an unpolarized small-angle neutron scattering (SANS) study on Mn-Zn ferrite (MZFO) magnetic nanoparticles with the aim to elucidate the interplay between t…
Supraferromagnetic correlations in clusters of magnetic nanoflowers
Philipp Bender, Dirk Honecker, Luis Fernández Barquín
Magnetic nanoflowers are densely packed aggregates of superferromagnetically coupled iron oxide nanocrystallites, which excel during magnetic hyperthermia experiments. Here, we inv…
Effect of grain-boundary diffusion process on the geometry of the grain microstructure of NdFeB nanocrystalline magnets

Hot-deformed anisotropic NdFeB nanocrystalline magnets have been subjected to the grain-boundary diffusion process (GBDP) using a eutectic…
The magnetic structure factor of correlated moments in small-angle neutron scattering
Dirk Honecker, Luis Fernández Barquín, Philipp Bender
The interplay between structural and magnetic properties of nanostructured magnetic materials allows to realize unconventional magnetic effects, which results in a demand for exper…
