Abstract

The structure of C-form Ho2O3 and Er2O3 single crystals and powder samples was investigated by the electric quadrupole hyperfine interaction of111In(EC)111Cd probe ions using the perturbed γ-γ angular correlation method (PAC). The resulting set of refined atomic coordinates is compared to X-ray data and used to calculate the orientations of the electric field gradients (EFG) which are reproduced by the PAC measurements in single crystals. The temperature dependence of the coordinates was measured for both substances.
