We have performed powder diffraction measurement on the typical spin-glass system Mn$$_{0.5}$$Fe$$_{0.5}$$TiO$$_3$$ using the neutron total scattering spectrometer NOVA installed in J-PARC to apply the mPDF analysis to the short-range correlation in the spin-glass phase. The mPDF obtained from the magnetic scattering intensity can be reproduced by the linear combination of the mPDFs calculated from the antiferromagnetic structures of MnTiO$$_3$$ and FeTiO$$_3$$, consistent with the coexistence of two different antiferromagnetic correlations in the spin-glass phase.
