Ising transition in the two-dimensional quantum $J_{1} - J_{2}$ Heisenberg model

Luca Capriotti, Tommaso Roscilde, Andrea Fubini +1

We study the thermodynamics of the spin- $S$ two-dimensional quantum Heisenberg antiferromagnet on the square lattice with nearest ( $J_{1}$ ) and next-nearest ( $J_{2}$ ) neighbor coupling…

Anisotropy and Ising-like transition of the S=5/2 two-dimensional Heisenberg antiferromagnet Mn-formate di-Urea

Alessandro Cuccoli, Tommaso Roscilde, Valerio Tognetti +2

Recently reported measurements of specific heat on the compound Mn-formate di-Urea (Mn-f-2U) by Takeda et al. [Phys. Rev. B 63, 024425 (2001)] are considered. As a model to describ…
