    "abstract": "The thermal entanglement of a two-qubit anisotropic Heisenberg $XYZ$ chain\nunder an inhomogeneous magnetic field b is studied. It is shown that when\ninhomogeneity is increased to certain value, the entanglement can exhibit a\nlarger revival than that of less values of b. The property is both true for\nzero temperature and a finite temperature. The results also show that the\nentanglement and critical temperature can be increased by increasing\ninhomogeneous exteral magnetic field.",
