Abstract

The thermal expansion of beta -AgI single crystals has been measured from 4 to 270K along the c direction, and is found to be negative throughout the range. The results are explained in terms of the negative Gruneisen gamma s which have been reported for both transverse acoustic and optic modes in beta -AgI.
