We report on the low-temperature magnetic susceptibilities and specific heats of the isostructural spin-ladder molecular complexes L$_{2}$[M(opba)]$_{3\cdot x$DMSO$\cdot y$H$_{2}$O, hereafter abbreviated with L$_{2}$M$_{3}$ (where L = La, Gd, Tb, Dy,

Influence of the lattice geometry on the thermodynamical properties of two-dimensional spin systems

Autor: Mombelli, B., Kahn, O., Leandri, J., Leroyer, Y., Mechkov, S., Meurdesoif, Y.

Various types of mixed spin two-dimensional Heisenberg networks are investigated by means of Monte Carlo simulations. This study aims at interpreting quantitatively the thermodynamical properties of two-dimensional molecule-based magnets recently syn

Thermodynamics of a mixed quantum-classical Heisenberg model in two dimensions

Autor: Leandri, J., Leroyer, Y., Meshkov, S. V., Meurdesoif, Y., Kahn, O., Mombelli, B., Price, D.

We study the planar antiferromagnetic Heisenberg model on a decorated hexagonal lattice, involving both classical spins (occupying the vertices) and quantum spins (occupying the middle of the links). This study is motivated by the description of a re
