| 英文摘要 | The thermal entanglement in a two-qubit spin-1 system with two spins coupled by exchange interaction is investigated in terms of the measure of entanglement called "negativity". it is found that the thermal entanglement exists and is symmetric for both ferromagnetic and antiferromagnetic exchange couplings. moreover, the critical temperature at which the negativity vanishes increases with the exchange coupling constant j. from the temperature and magnetic field dependences we demonstrate that the temperature and the magnetic field can affect the feature of the thermal entanglement significantly.
