On Debye temperature anomaly observed in Ge-Se-Ag glasses

Abstract

Anomalous Values of Debye temperature have been obtained from Lamb Mossbauer factor measurements of Ge-Se-Ag glasses. We show that this anomaly may arise due to the presence of anharmonic potential at the high spin ferrous site. In this paper, we use q Lamb Mossbauer factor and anharmonic Lamb Mossbauer factor to study this anharmoncity.
