The square-kagome quantum Heisenberg antiferromagnet at high magnetic fields: the localized-magnon paradigm and beyond
We consider the spin-1/2 antiferromagnetic Heisenberg model on the two-dimensional square-kagome lattice with almost dispersionless lowest magnon band. For a general exchange coupling geometry we elaborate low-energy effective Hamiltonians which emerge at high magnetic fields. The effective model to...
