Abstract We employ entanglement negativity, local quantum uncertainty (LQU), and local quantum Fisher information (LQFI) to characterize thermal entanglement between two XYZ-Heisenberg-qubit states under the influence of Dzyaloshinsky–Moriya(DM) and Kaplan–Shekhtman–Entin-Wohlman–Aharony (KSEA) interactions, as well as a magnetic field, and thermal equilibrium temperature. A comparative examination reveals similar behaviors among these correlation measures. For the antiferromagnetic scenario, we observe that increasing the DM interaction parameter $D_{z}$ enhances thermal entanglement. Conversely, in the ferromagnetic case, the behavior of thermal entanglement differs with varying $D_{z}$. Additionally, employing Kraus operators, we explore the performance of these quantifiers under decoherence. Notably, LQFI exhibits greater robustness than negativity and LQU, even displaying a frozen phenomenon at some time under dephasing effects.
