  We have considered the 1D spin-1/2 Ising model with added
Dzyaloshinskii-Moriya (DM) interaction and presence of a uniform magnetic
field. Using the mean-field fermionization approach the energy spectrum in an
infinite chain is obtained. The quantum discord (QD) and concurrence between
nearest neighbor (NN) spins at finite temperature are specified as a function
of mean-field order parameters. A comparison between concurrence and QD is done
and differences are obtained. The macroscopic thermodynamical witness is also
used to detect quantum entanglement region in solids within our model. We
believe our results are useful in the field of the quantum information
processing.
