| Abstract: | Conversion electron Mössbauer measurements with a proportional counter at 6.3, 78 and 300 K have been done to investigate the magnetic properties of the corrosion products formed on the surface of iron foils, which consist of small particles of γ-Fe2O3. The growing period of the corroded layer formed in a solution of low oxygen concentration has insignificant influence on the size of particles composing the layer, however, when the corroded layer is grown in a solution of comparatively high oxygen concentration, the particle size becomes large with growing period of the layer. |
