متن کاملSusceptibilities, Correlation Functions and Neutron Scattering Law in Amorphous Magnets
-We caJculated the static and dynamic susceptibilities x (Q) and x (Q, w) , the neutron scattering cross-section S (Q) , and the scattering law S (Q, w ) for amorphous magnets with small random anisotropy. These results agree fairly well with those of a recent neutron-spin echo experiment on amorphous TbNiz. Amorphous magnets with random anisotropy commonly are described by the random anisotrop...
متن کاملSmall-angle neutron scattering correlation functions of bulk magnetic materials
On the basis of the continuum theory of micromagnetics, the correlation function of the spin-misalignment small-angle neutron scattering cross section of bulk ferromagnets (e.g. elemental polycrystalline ferromagnets, soft and hard magnetic nanocomposites, nanoporous ferromagnets, or magnetic steels) is computed. For such materials, the spin disorder which is related to spatial variations in th...
متن کاملRotational dynamics of propane in Na-Y zeolite: a molecular dynamics and quasielastic neutron-scattering study.
We report results from molecular dynamics (MD) simulations and quasielastic neutron-scattering (QENS) measurements on the rotational dynamics of propane in Na-Y zeolite at room temperature with a loading of four molecules per alpha cage. Rotational part of the intermediate scattering function F(Q,t) obtained from the MD simulation suggests that rotational motion is faster relative to the transl...
متن کاملSpherical momentum distribution of the protons in hexagonal ice from modeling of inelastic neutron scattering data.
The spherical momentum distribution of the protons in ice is extracted from a high resolution deep inelastic neutron scattering experiment. Following a recent path integral Car-Parrinello molecular dynamics study, data were successfully interpreted in terms of an anisotropic Gaussian model, with a statistical accuracy comparable to that of the model independent scheme used previously, but provi...
