The Fe3O4 nanoparticles, incorporated into two diamagnetic glasses (TeO2–PbO–B2O3 and PbO–Bi2O3–B2O3) by DC magnetron sputtering, were annealed at 300 °C for 22 h in order to investigate the influence to the thermal stability and magneto-optical properties of glasses. The structure, morphology and magnetic properties of two sputtered glasseswere compared and characterized using X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), andUV–VIS spectrameasurements. The Verdet constant of glasseswasmeasured by a home-made optical bench. Sputtered samples (Fe3O4 target)were comparedwith the one obtained by melt-quenching Fe3O4 nanoparticles. The influence of sputtered Fe3O4 layer thickness on thermal and magneto-optical performance was investigated. The results prove that the magnetic property of both glasses, and especially the TeO2–PbO–B2O3 one, is enhanced after the incorporation of 1–5 μm-thick-Fe3O4 layer deposited by sputtering. Compared with the uncoated glasses, no significant degradation in FT-IR transmittance, UV–VIS absorption and thermal stability were discovered. The TeO2–PbO–B2O3–Fe3O4 system exhibits the best thermal and magneto-optical performances for magneto optical applications, within the two glass families.
