2.6. Real-space PDF calculation as a back-Fourier transform In the case of neutron scattering, the PDF calculation formalism is straightforward, as described by Keen (2001). This is because the neutron scattering length b is invariant with scattering vector magnitude Q. In the case of X-ray scattering, the atomic form factor f(Q) shows strong damping with Q and the Q dependence differs for different elements.

The enantiomorphous (chiral) crystal class of Sohncke-type Pb(TiO)Cu4(PO4)4 permits the rotation of the plane of polarization of light (optical activity). Copper ions participate in noncollinear antiferromagnetic order below a temperature ≈ 7 K, with magnetoelectric and piezomagnetic effects permitted.

Abstract We present a study of the lattice dynamical properties of Mn1−xFexSi with 0≤x≤0.22. Employing time-of-flight neutron spectroscopy and inelastic x-ray scattering, we investigate the doping dependence of phonon energies, Eph, and linewidths, Γph. We find anomalous softening and broadening of a phonon mode propagating along the [111] direction.

Motivated by the classical spin-nematic state observed in the breathing pyrochlore spinel LiGa0.95In0.05Cr4O8, we theoretically discuss spin dynamics in models of spin-lattice coupling in these materials. Semiclassical dynamical simulations successfully recover the key features of inelastic neutron-scattering experiments on LiGa0.95In0.05Cr4O8: a broad finite-energy peak alongside a continuum of scattering near the (200) wave vector that extends from the elastic line to high energies.

We investigate the magnetic properties of the monoclinic D-type Er2Si2O7 with a distorted honeycomb lattice using powder and single-crystal neutron scattering techniques, as well as single-crystal magnetization measurements. The powder neutron diffraction shows that below the ordering temperature, TN=1.85K, the compound forms a q=0 antiferromagnetic structure with four sublattices.

Thermally activated structural phase transitions and processes in metal–organic frameworks
The structural knowledge of metal–organic frameworks is crucial to the understanding and development of new efficient materials for industrial implementation. This review classifies and discusses recent advanced literature reports on phase transitions that occur during thermal treatments on metal–organic frameworks and their characterisation.

Using a high-accuracy variational Monte Carlo approach based on group-convolutional neural networks, we obtain the symmetry-resolved low-energy spectrum of the spin-1/2 Heisenberg model on several highly symmetric fullerene geometries, including the famous C60 buckminsterfullerene.

CeNiSn is a Kondo semimetal where a gap opens at low temperatures due to hybridization between 4f and conduction electrons, but a full insulating state fails to develop. Upon the insertion of hydrogen, long-range magnetic order is induced. Here we report zero-field muon spin relaxation and inelastic neutron scattering measurements of polycrystalline samples of the deuterides CeNiSnDx (x=1.0,1.8).
