The thermal entanglement in the spin-S Heisenberg XY Z model is studied in detail by using the entanglement measure of negativity.The effects of spin on the thermal entanglement,the threshold temperature,the critical uniform exteal magnetic field,the nonuniform exteal magnetic field and the entanglement extremum are discussed,respectively.It is shown that with increasing spin,the entanglement will increase,and then decrease slowly.In addition,we find that entanglement will approach a constant Nc with the increase of DM interaction,the constant increases with the increase of spin,and both the threshold temperature Tc and critical uniform exteal magnetic field Bc will increase with the increasing spin.Thus high-spin system can inhibit the influence of the exteal environment better.
