| 中文摘要 | the thermal entanglement in a two-spin-qutrit system with two spins coupled by exchange interaction is investigated in terms of the measure of entanglement called 'negativity'. we strictly show that for any temperature the entanglement is symmetric with respect to zero magnetic field. the behavior of negativity is presented for four different cases. we find that the entanglement may be enhanced under a nonuniform magnetic field. because there is not any necessary and sufficient condition for quantum separability in systems of dimension 3 circle times 3, our results are qualitative, not quantitative.
