Abstract
Measurements of dipole relaxation of two types of -interstitial complexes in single crystals using the ionic-thermocurrents method are reported. For the light elements in the series of lanthanides we have found relaxations due to tetragonal complexes, whereas in crystals doped with heavy ions such as , , etc., the predominant defects have trigonal symmetry. The variation of the activation energy as a function of the radius is discussed. In addition, the effect of the impurity concentration on the relaxation parameters is studied.
