Frustration-induced degenerate spin state with up-up-down-down ordering in corner-connected Heisenberg square-plaquettes
Pritam Manna, A. K. Bera
We investigate frustrated magnetism of a corner-connected square plaquette Heisenberg model with exchange interactions along the edges , along inter-plaquette links ,…

Neutron scattering evidence for two-dimensionally coupled spin-dimerized antiferromagnetic lattice in α-Cu2P2O7
B. Ghanta, K. S. Chikara, M. Ghanathe +3
The microscopic magnetic model of the low-dimensional quantum magnet alpha-Cu2P2O7 has remained controversial. We present a comprehensive study of its magnetic ground state and exc…
