摘      要：Thermal entanglement of a two-qubit Ising chain subjected to an external magnetic field and Dzyaloshinsky–Moriya(DM)interaction is *** effect of magnetic field,strength of DM interaction and temperature are analyzed by adopting negativity of partial transpose as the measure of *** is shown that when the DM interaction along the Ising axis is considerable,thermal entanglement can be sustained for a higher *** usefulness of longitudinal DM interaction over the one that is perpendicular to the Ising axis,in the manipulation and control of entanglement at a feasible temperature,is illustrated.
