The non-equilibrium thermal entanglement and quantum discord in a two-qubit Heisenberg XYZ model subjected to two thermal baths with different temperatures are investigated. The dynamical behaviors of entanglement and quantum discord under the influences of the initial states of the two-qubit system, the temperature of the thermal baths and the coupling constant $$J_z$$ J z are discussed. A special emphasis is devoted to study the effects of the thermal baths on the steady quantum correlation between the two qubits. Our results show that the temperature difference $$\Delta T$$ Δ T plays a key role for the appearance of steady quantum correlation, which can be enhanced by coupling constant $$J_z$$ J z , DM interaction and non-uniform magnetic field.
