In this study, pulsed NMR is used to probe the hyperfine
interactions in liquid Se₀₅Te₀₅ doped with 3% Ga over the
temperature range from 500 °C to 900 °C. Both resonance shifts and
relaxation times are determined for ⁷⁷Se, ⁷¹Ga and ⁶⁹Ga.
NMR on both Ga-isotopes allows one to measure...
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...
YBa₂Cu₃0₇₋x was doped with In by a stoichiometrically exact substitution of
Y by In, doping levels ranging from 0% to 20%. Room temperature X-ray diffraction
measurements, Perturbed Angular Correlation spectroscopy using ¹¹¹Cd as nuclear
tracer at a variety of temperatures ranging from room temperature to 950°C and magnetic
flux exclusion...
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...
Perturbed Angular Correlation Spectroscopy (PAC) is a highly sensitive local
probe technique well suited for studying defect characteristics of solids. This technique is
applied to the problem of studying the solubility of indium in cerium oxide. Through the
measurement of samples with differing levels in indium doping, the solubility of...
