Itinerant Antiferromagnetism in RuO
T. Berlijn, P. C. Snijders, O. Delaire +9
Bulk rutile RuO has long been considered a Pauli paramagnet. Here we report that RuO exhibits a hitherto undetected lattice distortion below approximately 900 K. The distor…
Phonon anharmonicity and negative thermal expansion in SnSe
Dipanshu Bansal, Jiawang Hong, Chen W. Li +5
The anharmonic phonon properties of SnSe in the Pnma phase were investigated with a combination of experiments and first-principles simulations. Using inelastic neutron scattering…
Electronic Instability and Anharmonicity in SnSe
Jiawang Hong, Olivier Delaire
The binary compound SnSe exhibits record high thermoelectric performance, largely because of its very low thermal conductivity. The origin of the strong phonon anharmonicity leadin…
Weak coupling of pseudoacoustic phonons and magnon dynamics in incommensurate spin ladder compound Sr14Cu24O41
Xi Chen, Dipanshu Bansal, Sean Sullivan +5
Intriguing lattice dynamics has been predicted for aperiodic crystals that contain incommensurate substructures. Here we report inelastic neutron scattering measurements of phonon…
Modeling non-harmonic behavior of materials from experimental inelastic neutron scattering and thermal expansion measurements
Dipanshu Bansal, Amjad Aref, Gary Dargush +1
Based on thermodynamic principles, we derive expressions quantifying the non-harmonic vibrational behavior of materials, which are rigorous yet easily evaluated from experimentally…
