The Hida model, defined on a honeycomb lattice, is a spin-1/2 Heisenberg model of aniferromagnetic hexagons (with nearest-neighbor interaction, ${J}_{A}g0)$ coupled via ferromagnetic bonds (with exchange interaction, ${J}_{F}l0)$. It applies to the spin-gapped organic materials, $\mathrm{m}\text{\ensuremath{-}}\mathrm{MPYNN}\ifmmode\cdot\else\textperiodcentered\fi{}X$ (for $X=\mathrm{I},{\mathrm{BF}}_{4},{\mathrm{ClO}}_{4})$, and for $|{J}_{F}|\ensuremath{\gg}{J}_{A}$, it reduces to the spin-1… 

Competing orders in a frustrated Heisenberg model on the Fisher lattice

We investigate the Heisenberg model on a decorated square (Fisher) lattice in the presence of first neighbor $J_{1}$, second neighbor $J_{2}$, and third neighbor $J_{3}$ exchange couplings, with

Effective spin-1 breathing kagome Hamiltonian induced by the exchange hierarchy in the maple leaf mineral bluebellite

As a highly frustrated model Hamiltonian with an exact dimer ground state, the Heisenberg antiferromagnet on the maple leaf lattice is of high theoretical interest, and a material realization is
