DOI: 10.1103/physrevb.104.094416
Abstract: A spin-1/2 Heisenberg model on honeycomb lattice is investigated by doing triplon analysis and quantum Monte Carlo calculations. This model, inspired by Cu$_2$(pymca)$_3$(ClO$_4$), has three different antiferromagnetic exchange interactions ($J_A$, $J_B$, $J_C$) on three different… read more here.

DOI: 10.12693/aphyspola.137.625
Abstract: We present a simple model for a description of magnetization processes in metallic rare-earth tetraborides. It is based on the two-dimensional Ising model, in which two spins on the Shastry–Sutherland lattice interact via the long-range… read more here.
