From: Quantum coherence of the Heisenberg spin models with Dzyaloshinsky-Moriya interactions

(a) Coherence versus D z and J z in the x-basis for XYZ model with D z interaction for J x = −1.0, J y = −0.5 and T = 2.5. (b) Coherence versus D x and J x in the z-basis for the XYZ model with D x interaction when J y = −0.5, J z = −1.0 and T = 2.5.
