FORC analysis of Ni(SiO2) nanogranular film in the blocked regime

► FORC study of Ni nanoparticles in the blocked regime. ► The sample is composed of Ni nanoparticles with 3.7 nm in average size. ► The dispersion of sizes of nanoparticles is wide. ► FORC diagrams show a distribution of coercivity consistent with the distribution of sizes.
