    Notes: Abstract Mössbauer spectra and electrical conductivities were measured for the purpose of studying on the conduction mechanism of xFe2O3−(40-x)V2O5−60P2O5 glasses. The ratios Fe2+/Fe2++Fe3+ in xFe2O3−(40-x)V2O5−60P2O5 glasses were determined by Mössbauer spectroscopy. On the composition dependence of D. C. conductivities in these glasses, the minimum of log σ at each temperature was obtained at 25Fe2O3−15V2O5−60P2O5. The conductivities of ternary glassses in Fe rich region could be explained only by the changes of carrler (Fe2+) concentration and the hopping conduction between Fe2+ ions and Fe3+ ions in binary glasses. In V rich region, the saturation tendency of D. C. conductivities are observed. It was suggested to be explained by increasing of V4+ ions due to the influence of Fe ions.

    Notes: Abstract Mössbauer parameters such as the line width and the absorption area of SUS 304 foils were observed to increase below 60K, but the change of the isomer shift below 60 K was not observed. The broadening of the line width were attributed to the effect of the magnetic transition at near 60K. On the increasing of the absorption area below 60K, two reasons were suggested. One is the increasing of the recoilless fraction of austenitic phase due to the magnetostriction effect. The other is that there is an unassigned phase below 60K and this phase come from interstitial trapping of57Fe atoms which move in the cage.
