Non-collinear 2k antiferromagnetism in the Zintl semiconductor EuInSb
Vincent C. Morano, Jonathan Gaudet, Nicodemos Varnava +10
EuInSb is an orthorhombic non-symmorphic small band gap semiconductor with three distinct Eu sites and two low-temperature magnetic phase transitions. The materi…
Band-Mott mixing hybridizes the gap in FeMoO
K. Park, G. L. Pascut, G. Khanal +9
We combined optical spectroscopy and first principles electronic structure calculations to reveal the charge gap in the polar magnet FeMoO. Iron occupation on the octah…
Phonon spectrum of PrZrO and PrIrO as an evidence of coupling of the lattice with electronic and magnetic degrees of freedom
Yuanyuan Xu, Huiyuan Man, Nan Tang +5
Magnetic materials with pyrochlore crystal structure form exotic magnetic states due to the high lattice frustration. In this work we follow the effects of coupling of the lattice…
Orbital-selective Mott phase and non-Fermi liquid in FePS
Minsung Kim, Heung-Sik Kim, Kristjan Haule +1
The layered metal phosphorous trisulfide FePS is reported to be a Mott insulator at ambient conditions and to undergo structural and insulator-metal phase transitions under pre…
Importance of dynamic lattice effects for crystal field excitations in quantum spin ice candidate PrZrO
Yuanyuan Xu, Huiyuan Man, Nan Tang +5
PrZrO is a pyrochlore quantum spin-ice candidate. Using Raman scattering spectroscopy we probe crystal electric field excitations of Pr, and demonstrate the impo…
Incommensurate magnetism mediated by Weyl fermions in NdAlSi
Jonathan Gaudet, Hung-Yu Yang, Santu Baidya +11
Emergent relativistic quasiparticles in Weyl semimetals are the source of exotic electronic properties such as surface Fermi arcs, the anomalous Hall effect, and negative magnetore…
