Abstract
Perturbed angular correlation measurements in the HfAl2 C14-type Laves phas e exhibit a very surprising temperature behavior of the ion-implanted In-11 1 probe atoms. Below 370 K the In-111 impurities are located at the unique hafnium site. Above 400 K they occupy the two aluminum sites, however with a clear preference of the 2(a) site. This process, which is fully reversibl e when heating and cooling the sample, is attributed to atomic size effects . (C) 2001 Elsevier Science B.V. All rights reserved.
