摘要：

Perturbed-angular-correlation (PAC) measurements with In-111(EC)Cd-111 probes, implanted at 400 keV into poly- or mono-crystalline Cr2O3, have been carried out as a function of temperature (290-1370 K). Two different electric-field gradients (e.f.g.'s) with identical orientations in the lattice have been found. Their temperature-dependent variations can be well described by a dynamical model which we propose to be connected with a hole trapping at a next-neighbour Cr ion.
