Room-Temperature $^{181}$Ta(TiO$_2$): An e-γ TDPAC Study
/ Yap, Ian Chang Jie (Gottingen U., II. Phys. Inst.) ; Schell, Juliana (CERN ; Duisburg-Essen U.) ; Dang, Thien Thanh (Duisburg-Essen U.) ; Noll, Cornelia (Bonn U., HISKP) ; Beck, Reinhard (Bonn U., HISKP) ; Köster, Ulli (Laue-Langevin Inst.) ; Mansano, Ronaldo (Sao Paulo U.) ; Hofsäss, Hans Christian (Gottingen U., II. Phys. Inst.)
In this work, we report on the hyperfine parameters of the foreign 181Ta probe in the rutile structure of the single crystal TiO2 using the e−γ and γ−γ time differential perturbed angular correlation (TDPAC) technique. We implanted 181Hf ions into a sample of single crystal rutile TiO2 in the Bonn Isotope Separator. [...]

The electric-field gradient (EFG) at nuclei in solids is a sensitive probe of the charge distribution. Experimental data, which previously only existed in insulators, have been available for metals with the development of nuclear measuring techniques since about 1970. [...]

In this paper, we present a study of the temperature-dependent characteristics of electromagnetic fields at the atomic scale in multiferroic bismuth ferrite (BiFeO$_3$ or BFO). The study was performed using time differential perturbed angular correlation (TDPAC) spectroscopy on implanted 111In (111Cd) probes over a wide temperature range. [...]
