Diffraction from nanocrystal superlattices
Antonio Cervellino, Ruggero Frison
Diffraction from a lattice of periodically spaced crystals is a topic of current interest because of the great development of self-organised superlattices (SL) of nanocrystals (NC)…
Dynamic Magnetic Crossover at the Origin of the Hidden-Order in van der Waals Antiferromagnet CrSBr
Sara A. López-Paz, Zurab Guguchia, Vladimir Y. Pomjakushin +6
The van der Waals material CrSBr stands out as a promising two-dimensional magnet. Especially, its high magnetic ordering temperature and versatile magneto-transport properties mak…
Structural disorder and magnetic correlations driven by oxygen doping in Nd2NiO4+d (d ~ 0.11)
Sumit Ranjan Maity, Monica Ceretti, Lukas Keller +7
We investigated the influence of oxygen over-stoichiometry on apical oxygen disorder and magnetic correlations in Nd2NiO4+d (d~0.11) in the temperature range of 2-300 K by means of…
Tetragonal mixed system complemented by the tetragonal phase realisation of
Natalija van Well, Claudio Eisele, Sitaram Ramakrishnan +6
Realisation of the tetragonal phase of is possible using specific crystal growth conditions at a temperature below . This work deals with the comparison of the m…
A dilute gold nanoparticles suspension as SAXS standard for absolute scale using an extended Guinier approximation
Ahmed S. A. Mohammed, Agnese Carino, Andrea Testino +2
In this article, a practical procedure for absolute intensity calibration for SAXS studies on liquid microjets is established, using a gold nanoparticle suspension as standard so t…
In-situ liquid SAXS studies on the early stage of calcium carbonate formation
Ahmed Shaban Abdelfadil Mohammed, Agnese Carino, Andrea Testino +2
Calcium carbonate is a model system to investigate the mechanism of solid formation by precipitation from solutions, and it is often considered in the debated classical and non-cla…
First principles calculation and experimental investigation of lattice dynamics in the rare earth pyrochlores R2Ti2O7 (R=Tb, Dy, Ho)
M Ruminy, M Nunez Valdez, B Wehinger +15
We present a model of the lattice dynamics of the rare earth titanate pyrochlores R2Ti2O7 (R=Tb, Dy, Ho), which are important materials in the study of frustrated magnetism. The ph…
Cube-shape diffuse scattering and the ground state of
A. Cervellino, S. N. Gvasaliya, B. Roessli +6
A quite unusual diffuse scattering phenomenology was observed in the single-crystal X-ray diffraction pattern of cubic perovskite BMT ($\mathrm{BaMg}_{1/3}\mathrm{Ta}_{2/3}\mathrm{…
The Structure and Low-Energy Phonons of the Nonferroelectric Mixed Perovskite: BaMg1/3Ta2/3O3
A. Cervellino, S. N. Gvasaliya, B. Roessli +5
The structure of BaMg1/3Ta2/3O3 (BMT) has been studied using X-ray scattering. The phonons have been measured and the results are similar to those of other materials with the perov…
Diffuse scattering from the lead-based relaxor ferroelectric PbMg_1/3Ta_2/3O_3
A. Cervellino, S. N. Gvasaliya, O. Zaharko +6
The relaxor ferroelectric PbMg_1/3Ta_2/3O_3 was studied by single-crystal neutron and synchrotron x-ray diffraction and its detailed atomic structure has been modeled in terms of s…
