Dynamic moiré-like band modulation in Dirac materials via multi-beam optical interference
Evelyn P. Sinaga, Rizky Setiawan, Herri Trilaksana +2
We propose a purely optical Floquet framework to dynamically generate moiré-like superlattices and quasicrystalline potentials in a gapped Dirac material, entirely bypassing the ne…
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…
Neutron-scattering signature of the Dzyaloshinskii-Moriya interaction in nanoparticles
Evelyn Pratami Sinaga, Michael P. Adams, Eddwi H. Hasdeo +1
The antisymmetric Dzyaloshinkii-Moriya interaction (DMI) arises in systems with broken inversion symmetry and strong spin-orbit coupling. In conjunction with the isotropic and symm…
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…
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…
