Negative thermal expansion and oxygen disorder in cubic ZrMo2O8

Allen, S.; Evans, J.S.O.

Abstract

In this paper we report precise thermal expansion data for the cubic negative thermal expansion material gamma-ZrMo2O8 which has an average expansion coefficient of -6.9x10(-6) K-1 between 2 and 200 K and -5.0x10(-6) K-1 between 250 and 502 K. Thermal expansion data give strong evidence for the presence of dynamic oxygen disorder in this material at temperatures of 200 K and above.
