| Abstract: | Mössbauer effect and susceptibility measurements have been performed from 1.4 K up to 300 K on Na Borosilicate glasses with 4, 8, 12, 20% by weight of Fe2O3 content. Besides some small isolated paramagnetic Fe2+ species, two Fe3+ particle distributions coexist with some isolated Fe3+ ions. Attempts have been made to give a chart of the particle size distribution in all samples. |
