Fast broadband cluster spin-glass dynamics in PbFeNbO
C. Stock, B. Roessli, P. M. Gehring +11
PbFeNbO (PFN) is a relaxor ferroelectric (T 400 K) consisting of disordered magnetic Fe (S=, L0) ions resulting in a l…
Probing the Manipulation of Antiferromagnetic Order in CuMnAs Films Using Neutron Diffraction
Stuart F. Poole, Luke X. Barton, Mu Wang +7
We describe measurements of the uniaxial magnetic anisotropy and spin-flop rotation of the Néel vector in antiferromagnetic CuMnAs thin films using neutron diffraction. The suppres…
Effective decoupling of ferromagnetic sublattices by frustration in Heusler alloys
F. Cugini, S. Chicco, F. Orlandi +10
Magnetic frustration in ferromagnetic metallic systems is unusual due to the long-range and symmetric nature of the exchange interactions. In this work we prove that it is possible…
A combined inelastic neutron scattering and \textit{ab initio} lattice dynamics study of FeSi
Nazir Khan, Sven Krannich, Dominic Boll +5
The phonon renormalization across the semiconductor-to-metal crossover in FeSi is investigated by inelastic neutron scattering combined with \textit{ab-initio} lattice dynamical ca…
Using small-angle scattering to guide functional magnetic nanoparticle design
Dirk Honecker, Mathias Bersweiler, Sergey Erokhin +8
Magnetic nanoparticles offer unique potential for various technological, biomedical, or environmental applications thanks to the size-, shape- and material-dependent tunability of…
Recovering the second moment of the strain distribution from neutron Bragg edge data
Kyle Fogarty, Evelina Ametova, Genoveva Burca +4
Point by point strain scanning is often used to map the residual stress (strain) in engineering materials and components. However, the gauge volume and hence spatial resolution is…
