The observation of bulk superconductivity in Rhombohedral ReO3 under pressure
S. Huyan, R. F. S. Penacchio, L-L. Wang +10
Understanding how lattice geometry enables superconductivity in oxides remains a central challenge. Here, we report a systematic study of ReO3 up to 80 GPa. Synchrotron X-ray diffr…
Benchtop Momentum-Resolved Phonon Spectroscopy: Unlocking Lattice Dynamics via X-ray Diffuse Scattering
Paulo H. V. da Silva, Tarsis M. Germano, Rafaela F. S. Penacchio +1
Momentum-resolved phonon spectroscopy is essential for understanding the thermal, electronic, and structural properties of materials, yet it traditionally necessitates access to la…
A practical Laser-Heated Diamond Anvil Cell synthesis technique and recovery workflow for metastable MnSb2 and YbZn2 phases
S. Huyan, R. F. S. Penacchio, D. Zhang +5
The creation and exploration of new materials under extreme pressure-temperature conditions has become increasingly reliant on laser-heated diamond anvil cell (LHDAC) techniques, w…
Itinerant antiferromagnetism in the antagonistic pair compound YCoAg
Rafaela F. S. Penacchio, Nao Furukawa, Joanna M. Blawat +7
Low dimensional crystallographic motifs have long been associated with desirable physical properties. The confinement of electrons to low dimensions is thought to enhance quantum f…
Structural phase transitions in the van der Waals ferromagnets FePdTe
Rafaela F. S. Penacchio, Siham Mohamed, Sérgio L. Morelhão +3
Here, we provide a detailed study of the crystal structure and physical properties of the recently discovered vdW ferromagnet FePdTe. We find this compound has a relatively…
Suppression of the valence transition in solution-grown single crystals of EuPtAl
Juan Schmidt, Dominic H. Ryan, Oliver Janka +7
The study of Eu intermetallic compounds has allowed the exploration of valence fluctuations and transitions in 4f electron systems. Recently, a EuPtAl phase synthesi…
Simulation of bright and dark diffuse multiple scattering lines in high-flux synchrotron X-ray experiments
M. B. Estradiote, A. G. A. Nisbet, R. F. S. Penacchio +3
We present a theoretical framework for understanding diffuse multiple scattering (DMS) in single crystals, focusing on diffuse scattering-Bragg (DS-Bragg) channels. These channels,…
Role of filler lanthanide ions on lattice dynamics of phosphide skutterudites RFeP (R = La, Ce, and Pr) from first principles
Rafaela F. S. Penacchio, Nicholas Burns, Maurício B. Estradiote +3
Phosphide skutterudites primarily show promise for thermoelectric applications due to their chemical stability at high temperatures and relatively low cost. Ion doping and band gap…
A simple recipe to create three-dimensional reciprocal space maps
Rafaela F. S. Penacchio, Maurício B. Estradiote, Sérgio L. Morelhão +5
Combinations of advanced X-ray sources and zero-noise detector of enormous dynamic range have significantly increased the opportunity of mapping the reciprocal space of crystal lat…
Proper usage of Scherrer's and Guinier's formulas in X-ray analysis of size distribution in systems of monocrystalline CeO2 nanoparticles
