Abstract:: Perturbed angular correlation (PAC) spectra of fully yttria-stabilized (cubic) zirconia with Y₂0₃ contents of 35.4 wt. %, 27.8 wt. %, and 16.9 wt. %, respectively, were measured using the isotope ¹⁸¹Ta as probe nucleus. PAC spectra in cubic zirconia are characterized by a wide frequency distribution due to contributions of...

Creator:: Dundon, Lisa
Abstract:: Perturbed Angular Correlations (PAC) spectroscopy is an effective local probe technique often employed in the characterization of defects or phase transitions in any of a variety of materials. This technique relies upon the ability of probe nuclei to function as gauges of the magnetic fields and electric field gradients local...

Abstract:: Perturbed angular correlation (PAC) spectroscopy of dilute zirconia alloys and YBa₂Cu₃0₇₋x, ceramic superconductors at elevated temperature have been measured using ¹¹¹Cd as the probe. The oxygen vacancy concentration in the zirconia samples was controlled by doping with yttrium or indium, which introduce vacancies, or with niobium, which removes vacancies. A...

Abstract:: Semi-insulating, powder samples of Cadmium Telluride (CdTe) have been studied using ¹¹¹In Time Differential Perturbed Angular Correlation (PAC) Spectroscopy. The samples have been lightly doped (~10¹² cm⁻³) with ¹¹¹In atoms, which occupy well-defined metal (Cd) lattice sites and act as probes of the local environment. These substitutional donors form a...
