Resumen:
The time-differential perturbed-angular-correlation technique is applied to study the hyperfine interaction of In111
atoms in stannic oxide. Two different preparation procedures were
employed to obtain high-purity samples. With both of them two static
quadrupole interactions are observed, characterized at room temperature
by the parameters ω1=31.1 Mrad/s, η1=0.45; ω2=14.3 Mrad/s, η2=0.65.
The temperature dependence of the hyperfine interaction is studied from
17 to 1173 K. The origin of the measured interactions is analyzed and
assigned to probe atoms substitutionally replacing Sn with singly and
doubly ionized oxygen vacancies as near neighbors.
