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…
Ab Initio Investigation of Pressure Effects in the Spin-Liquid Candidate Y-Kapellasite
Federico Abbruciati, Aleksandar Razpopov, Joao Elias F. S. Rodrigues +5
Motivated by recent experiments showing pressure-induced suppression of magnetic order and the emergence of a dynamical ground state in the anisotropic kagome antiferromagnet Y-kap…
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…
-RuCl intercalated into graphite: a new three-dimensional platform for exotic quantum phases
Aleksandar Razpopov, Shirin Mozaffari, Takahiro Matsuoka +5
Multilayer graphene with different stacking sequences has emerged as a powerful setting for correlated and topological phases. In parallel, progress in graphene heterostructures wi…
Altermagnetic splitting of magnons in hematite (-FeO)
Rhea Hoyer, P. Peter Stavropoulos, Aleksandar Razpopov +3
We develop a four-sublattice spin-wave theory for the -wave altermagnet candidate hematite (-FeO), considering both its easy-axis phase below and its weak ferromagne…
