A detailed structure analysis for the site-diluted SnxFe4-xN (x = 0.25, 0.41, and 0.88) has been carried out through complex modeling of the neutron total scattering data. We present quantitative evidence showing the local ferromagnetic cluster size extending to ~8 Å on average when Sn0.88Fe3.12N undergoes the spin-glass transition (the other two not showing such a transition). In conclusion, the modeling methodology used in this work involving the corefinement of the nuclear and magnetic structure in both real and reciprocal space can potentially be applied generally to explore a variety of spin-glass material problems.
