Abstract：
We study the global bipartite entanglement of the three-qubit Heisenberg XXX spin chain with impurity. Through calculating the negativities N_1-23 and N_12-3, we show that the critical temperature T_c above which the entanglement vanishes increases with the increase of the impurity parameter J₁. For a given T, the corresponding critical impurity parameter J_1c below which the entanglement vanishes increases with the increase of the magnetic field B, and by adjusting J₁ and B one can control the values of N_1-23 and N_12-3. The maximum value of N_12-3 decreases from 0.5 to 0.3727 as the temperature rises, but the one of N_1-23 keeps the constant value of about 0.4714.
