Twelve sublattice ordered phase in the J1-J2 model on the kagome lattice
Jean-Christophe Domenge, Philippe Sindzingre, Claire Lhuillier +1
Motivated by recent experiments on an S=1/2 antiferromagnet on the kagome lattice, we investigate the Heisenberg J1-J2 model with ferromagnetic J1 and antiferromagnetic J2. Classic…

Determination of the exchange energies in Li2VOSiO4 from a high-temperature series analysis of the square lattice J1-J2 Heisenberg model
G. Misguich, B. Bernu, L. Pierre
We present a high-temperature expansion (HTE) of the magnetic susceptibility and specific heat data of Melzi et al. on Li2VOSiO4 [Phys. Rev. B 64, 024409 (2001)]. The data are very…
