  Super-quantum discord is an extension of the quantum discord concept where
weak measurements are made instead of projective measurements. We study the
temperature behavior of the super-quantum discord for two real magnetic
materials. We extract information about super-quantum discord from the magnetic
susceptibility data for iron nitrosyl complexes $\mathrm{ Fe_2(SC_3
H_5N_2)_2(NO)_4}$ and binuclear Cu(II) acetate complex $\mathrm{[Cu_2
L(OAc)]\cdot 6 H_2O}$, where $\mathrm{ L}$ is a ligand that allows us to
compare the super-quantum discord with the standard one. The dependence of the
super-quantum discord on the parameter describing weak measurements is studied.
Obtained difference between super-quantum and quantum discords confirms the
detection of additional quantum correlations that are usually destroyed during
projective measurements. The use of the approach allows to predict
quantitatively in advance the advantages of use of weak measurements versus
projective one for quantum technologies in real settings where quantum discord
is used as resource. This can be relevant particularly in macroscopic quantum
systems where weak measurements can be used to extract information about the
system.
