    "abstract": "We study the thermal entanglement in a two-spin-qutrit system with anisotropy\nin the exchange coupling between two spins. We use the realignment criterion to\ndistinguish the entangled states, and the negativity for measuring the\nentanglement in this system. We see that the anisotropy can provide an\nadditional parameter for enhancing the entanglement.",
