Magnetic behavior of volborthite Cu3V2O7(OH)2(H2O)2 determined by coupled trimers rather than frustrated chains
O. Janson, S. Furukawa, T. Momoi +3
Motivated by recent experiments on volborthite single crystals showing a wide 1/3-magnetization plateau, we perform microscopic modeling by means of density functional theory (DFT)…
Microscopic magnetic modeling for the =1/2 alternating chain compounds NaCuSbO and NaCuTeO
M. Schmitt, O. Janson, S. Golbs +4
The spin-1/2 alternating Heisenberg chain system NaCuSbO features two relevant exchange couplings: within the structural CuO dimers and betwee…
Coupled frustrated quantum spin-1/2 chains with orbital order in volborthite Cu3V2O7(OH)2(H2O)2
O. Janson, J. Richter, P. Sindzingre +1
We present a microscopic magnetic model for the spin-liquid candidate volborthite Cu3V2O7(OH)2(H2O)2. The essentials of this DFT-based model are (i) the orbital ordering of Cu(1) 3…
Intrinsic peculiarities of real material realizations of a spin-1/2 kagome lattice
O. Janson, J. Richter, H. Rosner
Spin-1/2 magnets with kagome geometry, being for years a generic object of theoretical investigations, have few real material realizations. Recently, a DFT-based microscopic model…
