Abstract

Local fields in normal spinel oxides, CdFe2O4 and CdIn2O4, were measured by means of time-differential perturbed angular correlation spectroscopy with the 111In(→111Cd) and 111mCd(→111Cd) probes. The spectra obtained with the different probes show contrastive patterns in spite of the same daughter nuclei: the former shows static perturbations with explicit oscillatory structures, whereas for the latter, the angular correlations become gradually isotropic. The exponential-like relaxation patterns of the spectra observed for the 111mCd(→111Cd) probe suggest that the probes occupying the Cd A site experience time-dependent perturbation causing nuclear spin relaxation.
