Quetzalcoatlite as a Disorder-Free Platform for Chiral Magnetism and Frustration
Aleksandar Razpopov, P. Peter Stavropoulos, Michael R. Norman +1
The natural mineral quetzalcoatlite ZnCu(TeO)(OH) (AgPbCl) is a structurally ideal kagome magnet, providing a platform for exploring th…
Accessing Few-Layer CrI Magnetoelasticity Through Bulk Single Crystals
J. Arneth, M. Möller, D. A. S. Kaib +9
The persistence of ferromagnetic long-range order in monolayers of the van der Waals semiconductor CrI opens new routes for spintronic applications based on two-dimensional qua…
GHz non-reciprocal optical conductivity in hematite (-)
Peng Rao, Johannes Gröbmeyer, P. Peter Stavropoulos +5
We study the non-reciprocal properties of the iron oxide -FeO (hematite) in the canted easy-plane antiferromagnetic phase, specifically in the GHz to THz frequency rang…
Bobkingite, a new coupled sawtooth chain platform
P. Peter Stavropoulos, Aleksandar Razpopov, Harrison LaBollita +3
We investigate the mineral bobkingite, \ce{Cu5(OH)8Cl2(H2O)2}, as a potential realization of the sawtooth chain. Using \textit{ab initio} methods, we estimate the magnetic exchange…
Exact downfolding and its perturbative approximation
Jonas B. Profe, JakÅ¡a VuÄiÄeviÄ, P. Peter Stavropoulos +3
Solving the many-electron problem, even approximately, is one of the most challenging and simultaneously most important problems in contemporary condensed matter physics with vario…
Revealing the microscopic origin of the magnetization plateau in NaNiBiO
Amanda A. Konieczna, P. Peter Stavropoulos, Roser ValentÃ
Recent experimental studies of the spin-1 honeycomb antiferromagnet NaNiBiO have revealed a pronounced one-third magnetization plateau under applied magnetic fields, hi…
