  In this letter we study thermal quantum correlations as quantum discord and
entanglement in bipartite system imposed by external magnetic field with
Herring-Flicker coupling ie. $J(R)=1.642 e^{-2 R} R^{5/2}+O(R^{2}e^{-2R})$. The
Herring-Flicker coupling strength is the function of $R$, which is the distance
between spins and systems carry XXX Heisenberg interaction. By tuning the
coupling distance $R$, temperature and magnetic field quantum correlations can
be scaled in the bipartite system. We find the long sustainable behaviour of
quantum discord in comparison to entanglement over the coupling distance $R$.
We also investigate the situations, where entanglement totally dies but quantum
discord exist in the system. The present findings in the letter may be useful
for designing quantum wires, data bus, solid state gates and quantum
processors.
