  • Heat capacity, lattice dynamics, and thermodynamic stability of the negative thermal expansion material HfMo2O8 

    Kennedy, Catherine A., Mary Anne White, Angus P. Wilkinson, and Tamas Varga. 2007. "Heat capacity, lattice dynamics, and thermodynamic stability of the negative thermal expansion material HfMo2O8." Physical Review B 75(22): 224302-224302. Copyright © 2007 American Physical Society.
    We explore the lattice dynamics of the negative thermal expansion material, cubic HfMo2O8, through analysis of its heat capacity (measured from 0.5 to 300 K) and its room-temperature Raman spectrum. Its heat capacity is ...

  • Low thermal conductivity of the negative thermal expansion material, HfMo2O8 

    Kennedy, Catherine A., Mary Anne White, Angus P. Wilkinson, and Tamas Varga. 2007. "Low thermal conductivity of the negative thermal expansion material, HfMo2O8." Applied Physics Letters 90(15): 151906-151906.
    The thermal conductivity of the cubic polymorph of hafnium molybdate, HfMo2O8, was determined over the temperature range of 2-400 K. The values of thermal conductivity were low (0.64 +/- 0.15 W m(-1) K-1 at T=300 K for a ...
