Abstract

The anisotropy of the 133–182 keV γ-γ cascade in181Ta measured as a function of temperature between 70K and 298K shows lattice instability, the phenomenon of hysteresis in the vicinity of the lattice transformation temperature (TL) and a temperature dependent electric field gradient (EFG) at the cubic Hf sites in the superconducting cubic Laves phase (C15) compounds Hf1−xZrxV2 (x=0.0, 0.25 and 0.75). These observations are qualitatively understood by assuming the presence of γ-recoil effects and microdomains fluctuating between the high temperature (T>TL) and the low temperature (T < TL) phases of these compounds.
