Interplay of proximity effects in Superconductor/Ferromagnet heterostructures
725. WE-Heraeus-Seminar: Magnetic Small Angle Neutron Scattering – from Nanoscale Magnetism to Long‐Range Magnetic Structures, online eventonline event, online event, 31 May 2021 - 3 Jun 20212021-05-312021-06-03
Proximity effects in superconductor/ferromagnet thin film heterostructures are ahighly topical issue due to their potential application in superconducting spin valvesor fluxonic devices [1, 2]. Physical properties can be controlled by an appliedmagnetic field and emerge for example as stray-field generated domainsuperconductivityor spin-triplet correlations. [...]

Inelastic neutron scattering analysis with time-dependent Gaussian-field models
Converting neutron scattering data to real-space time-dependent structures can only be achieved through suitable models, which is particularly challenging for geometrically disordered structures. We address this problem by introducing time-dependent clipped Gaussian field models [...]

Unravelling Magnetic Nanochain Formation in Dispersion for In Vivo Applications
Advanced materials 33(24), 2008683 () [10.1002/adma.202008683]
Self-assembly of iron oxide nanoparticles (IONPs) into 1D chains is appealing, because of their biocompatibility and higher mobility compared to 2D/3D assemblies while traversing the circulatory passages and blood vessels for in vivo biomedical applications. In this work, parameters such as size, concentration, composition, and magnetic field, responsible for chain formation of IONPs in a dispersion as opposed to spatially confining substrates, are examined.

Chiral anomaly and anomalous Hall effect in Hexagonal-Mn3+δGe
IOP Magnetism 2021, online eventonline event, online event, 12 Apr 2021 - 13 Apr 20212021-04-122021-04-13
Chiral anomaly and anomalous Hall effect in Hexagonal-Mn3+δGeTopological quantum materials have attracted enormous attention since their discovery due to the observedanomalous transport properties, which originate from the non-zero Berry curvature. Mn3+δGe has gainedspecial attention because of its large anomalous transport effects that persist starting from Néel temperature(365 K) down to 2 K [1] [...]

Zinc determines dynamical properties and aggregation kinetics of human insulin
Protein aggregation is a widespread process leading to deleterious consequences in the organism, with amyloid aggregates being important not only in biology but also for drug design and biomaterial production. Insulin is a protein largely used in diabetes treatment, and its amyloid aggregation is at the basis of the so-called insulin-derived amyloidosis. [...]

Mutually Beneficial Combination of Molecular Dynamics Computer Simulations and Scattering Experiments
Membranes 11(7), 507 () [10.3390/membranes11070507]
We showcase the combination of experimental neutron scattering data and molecular dynamics (MD) simulations for exemplary phospholipid membrane systems. Neutron and X-ray reflectometry and small-angle scattering measurements are determined by the scattering length density profile in real space, but it is not usually possible to retrieve this profile unambiguously from the data alone.
