MOSSBAUER STUDIES IN SPUTTERED A-Fe//8//0B//2//0 FOILS.

Abstract

Mossbauer studies have been carried out on sputtered amorphous Fe//8//0B//2//0 foils in the temperature range of 4. 4 K to 300 K. The results have been analyzed using Window's method. The coefficients B and C in Bloch's law are evaluated from the data. One finds a smaller value of B in sputtered foils in comparison to the liquid quenched ribbons. There are indications that the mean square range of exchange interaction is larger in these foils.
