【 摘 要 】

This study investigates an orbital exciton propagation in quasi-two-dimensional Heisenberg antiferromagnet Sr2IrO4by means of computer simulation. Ising and Heisenberg models are compared, taking in consideration magnetic interactions and exciton hopping. As the result of this simulation the spin structure factor for both models is calculated.
