The critical values of ising model with the interaction of the second neighbor in the presence of DM interaction and magnetic field

摘要

The Ising three qubit model has been studied by the interaction of the second neighbor in the presence of DM interaction and external longitudinal uniform magnetic field. We've studied the critical values of DM interaction in the absence of magnetic field and also in the presence of magnetic field. In this case, it has been shown that the critical value of DM interaction depends on the exchange coefficient parameters and also the magnetic field. We've studied the critical value of the external longitudinal magnetic field per different cases of the exchange coefficients and DM interaction power. In has been shown that in some cases, there is no critical value of magnetic field.
