Grazing incidence neutron scattering for the study of solid–liquid interfaces
Reference Module in Chemistry, Molecular Sciences and Chemical Engineering / Wolff, Max ; : Elsevier, 2023, ; ISBN: 9780124095472 ; doi:10.1016/B978-0-323-85669-0.00014-3 Elsevier () [10.1016/B978-0-323-85669-0.00014-3]
Neutrons are characterized by a low absorption in many engineering materials. At the same time the scattering cross section of light elements, such as hydrogen and deuterium, may be large. [...]

Complementary insights from neutron and resonant X-Ray reflectometry for the study of perovskite transition‐metal oxide heterostructures
The non-destructive investigation of electronic and magnetic modifications at buried interfaces contributes significantly to our understanding of the underlying interactions. This knowledge is essential for the design of electronic devices based on complex quantum materials. [...]

Non-reciprocal magnons in non-centrosymmetric MnSi
AIP Advances 8(10), 101328 - () [10.1063/1.5041036]
Using two cold-neutron triple-axis spectrometers we have succeeded in fully mapping out the field-dependent evolution of the non-reciprocal magnon dispersion relations in all magnetic phases of MnSi. The non-reciprocal nature of the dispersion manifests itself in a full asymmetry (non-reciprocity) of the dynamical structure factor S(q,E,μ$_0$H$_{int}$) with respect to flipping either the direction of the applied magnetic field μ$_0$H$_{int}$, the reduced momentum transfer q, or the energy transfer E..

Role of the tuning parameter at magnetic quantum phase transitions
Heavy-fermion systems, with their competition betweenKondo and RKKY interactions, offer a rich variety of materials thatmay be driven to a magnetic quantum phase transition. Quite often,a quantum critical point can be approached by chemical substitution,notably of isoelectric ligands of Ce, as in CeCu6−xAux andCePd1−xNixAl. [...]
