Abstract:
An analysis of the energy spectrum and magnetization curve of the two-dimensional organic antiferromagnet F(2)PNNNO with a spin-one dimerized structure shows that the behavior of the compound in an external magnetic field can be explained within a lattice boson model with an extended Pauli exclusion principle, i.e. no more than two bosons per dimer. The unusual magnetization curve observed experimentally in the compound reflects a sequence of phase transitions intrinsic for a lattice boson system with strong on-site and inter-site repulsions due to a tuning of magnon density by the applied magnetic field.
