Here, using high-energy optical conductivity(up to 35 eV) as a function of temperature and polarization, we observe a surprisingly strong spin polarizationof the local spin singlet with enhanced ferromagnetic correlations between Cu spins near the doped holesin lightly hole-doped $La_{1.95}Sr_{0.05}Cu_{0.95}Zn_{0.05}O_4$.

Compared to cuvette measurements, the observed Raman signal is enhanced by more than one order of magnitude and does not contain signal distortions from the liquid-glass interface.
