Quantum Fisher information (QFI) and skew information (SI) plays a key rolein the quantum resource theory. Understanding these measures in the physicalsystem has practical significance in the state parameter estimation and quantummetrology. In this article, we consider a pair ofspin-1/2 particles coupledwith dipolar and Dzyaloshinsky-Moriya (DM) interactions, serving as thephysical carrier of quantum information. We examine the bipartite nonlocalcorrelations of pair of spin-1/2 particle system for the thermal equilibriumstates, characterized by local quantum uncertainty (LQU) and local quantumFisher information (lQFI). The effects of dipolar coupling constants on quantumcorrelation quantifiers are studied. The DM interaction greatly enhances thequantum correlation in the system whereas the temperature tends to annihilatethe amount of quantum correlations.
