    "abstract": "The effects of multi-impurity on the entanglement of anisotropic Heisenberg\nring XXZ under a homogeneous magnetic field have been studied. The impurities\nmake the equal pairwise entanglement in a ring compete with each other so that\nthe pairwise entanglement exhibits oscillation. If the impurities are of larger\ncouplings, both the critical temperature and pairwise entanglement can be\nimproved",
