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…
Unraveling the magnetic softness in Fe-Ni-B based nanocrystalline material by magnetic small-angle neutron scattering
Mathias Bersweiler, Michael P. Adams, Inma Peral +3
We employ magnetic small-angle neutron scattering to investigate the magnetic interactions in alloy, a HiB-NANOPERM-type soft magnetic nanocrystalli…
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…
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…
Effect of grain-boundary diffusion process on the geometry of the grain microstructure of NdFeB nanocrystalline magnets
Ivan Titov, Massimiliano Barbieri, Philipp Bender +6
Hot-deformed anisotropic NdFeB nanocrystalline magnets have been subjected to the grain-boundary diffusion process (GBDP) using a eutectic…
Evidence for the formation of nanoprecipitates with magnetically disordered regions in bulk Heusler alloys
Giordano Benacchio, Ivan Titov, Artem Malyeyev +12
Shell ferromagnetism is a new functional property of certain Heusler alloys which has been recently observed in . We report the res…
Crossover in the pressure evolution of elementary distortions in RFeO3 perovskites and its impact on their phase transition
R. Vilarinho, P. Bouvier, M. Guennou +9
This work reports on the pressure dependence of the octahedra tilts and mean Fe-O bond lengths in RFeO3 (R=Nd, Sm, Eu, Gd, Tb and Dy), determined through synchrotron X-ray diffract…
Microstructural-defect-induced Dzyaloshinskii-Moriya interaction
Andreas Michels, Denis Mettus, Ivan Titov +12
The antisymmetric Dzyaloshinskii-Moriya interaction (DMI) plays a decisive role for the stabilization and control of chirality of skyrmion textures in various magnetic systems exhi…
Spin structures of textured and isotropic Nd-Fe-B-based nanocomposites: Evidence for correlated crystallographic and spin texture
Andreas Michels, Raoul Weber, Ivan Titov +9
We report the results of a comparative study of the magnetic microstructure of textured and isotropic - nanocomposites using…
Amorphization induced by pressure: results for zeolites and general implications
Inmaculada Peral, Jorge Iniguez
We report an {\sl ab initio} study of pressure-induced amorphization (PIA) in zeolites, which are model systems for this phenomenon. We confirm the occurrence of low-density amorph…
