| Title: | Spatially frustrated S = 1 Heisenberg antiferromagnet with single ion anisotropy |
| Authors: | Antônio Sérgio Teixeira Pires |
| Abstract: | Using the SU(3) Schwinger boson formalism, I study the S = 1 square lattice Heisenberg antiferromagnet, at zero temperature, with spatially anisotropic nearest-neighbor couplings frustrated by a next-nearest neighbor interaction and single ion anisotropy. The phase diagram at zero temperature is presented. My calculations show two magnetically ordered phases separated by a quantum-disordered region for all values of the anisotropy. |
