Effect of Dzialoshinski-Moriya interaction on the quantum discord of a spin-star model

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