  A two-qubit Heisenberg XYZ model with Dzyaloshinsky-Moriya (DM) and
Kaplan-Shekhtman-Entin-Wohlman--Aharony (KSEA) interactions is considered at
thermal equilibrium. Analytical formulas are derived for the local quantum
uncertainty (LQU) and local quantum Fisher information (LQFI). Using the
available expressions for the entropic quantum discord, we perform a
comparative study of these measures of nonclassical correlation. Our analysis
showed the following: all three measures of quantum correlation have similar
qualitative and even quantitative behavior on temperature for different values
of system parameters, there are regions in the parameter space which
correspondent to a local increase of correlations with increasing temperature,
and sudden changes in the behavior of quantum correlations occur at certain
values of the interaction parameters.
