Abstract
We investigate the thermal entanglement in the two-qubit anisotropic XXZ model in the presence of an external inhomogeneous magnetic field along the z axis. Concurrence, the measurement of entanglement is calculated. The effects of the anisotropic parameter Δ on the thermal entanglement are studied carefully for both the antiferromagnetic and ferromagnetic cases. The critical temperature Tc can also be controlled by the anisotropic parameter Δ.
