Abstract
The perturbed angular correlation (PAC) technique has been used to characterize the degree of atomic order in the neighbourhood of radioactive 181Hf isotopes in HfW2O8. PAC measurements were carried out at temperatures between 14 and 723 K. The compound was synthesized starting with the oxides HfO2 and WO3, using a method involving ball milling, high temperature annealing and quenching in liquid nitrogen. Fast cooling allows to have the compound at temperatures below 1050 K. The compound has a high degree of stability below such temperature and around 430 K atomic ordering occurs. This transition order-disorder is reversible.
