Abstract
⺠Effect of DM interaction on quantum discord of a spin star model is studied. ⺠Quantum discord and thermal entanglement of a spin star model are compared. ⺠Increasing DM interaction can enhance the quantum discord and thermal entanglement. ⺠Increasing the magnetic field and temperature will shrink the quantum correlation. ⺠Quantum discord can survive higher temperatures than the thermal entanglement does.
