    "abstract": "We study the thermal entanglement in the two-qubit anisotropic XXZ model and\nthe Heisenberg model with Dzyaloshinski-Moriya (DM) interactions. The DM\ninteraction is another kind of anisotropic antisymmetric exchange interaction.\nThe effects of these two kinds of anisotropies on the thermal entanglement are\nstudied in detail for both the antiferromagnetic and ferromagnetic cases.",
