Abstract It has been shown that to account for the observed anharmonicity in the mean square displacement 〈 x 2 〉 of iron impurities in a copper host, it may be essential to consider the host impurity force constant changes. This suggests a modification of the relation 〈 x 2 〉 Imp = 〈 x 2 〉 Host valid at higher temperatures.
