TDPAC Studies of Local Defects and Phenomena in Ferroics and Multiferroics / Schell, Juliana (CERN ; Duisburg-Essen U.) ; Marschick, Georg (CERN ; TU Vienna)
We provide an overview of time-differential perturbed angular correlation (TDPAC) measurements of ferroic and multiferroic materials. Here, we explore chalcogenide spinels, lead titanate, lead zirconate, and bismuth ferrite, describing the use of TDPAC experiments to probe the physics of localized defects and the various mechanisms that govern electronic and magnetic interactions, the coupling of the associated degrees of freedom, and the structural, charge, and orbital correlations for these materials..

Duisburg-Essen) ; Escobar-Castillo, M (Duisburg-Essen U.) ; Noll, C (Bonn U., HISKP) ; Beck, R (Bonn U., HISKP) ; Zyabkin, Dmitry V (Ilmenau Tech. U.) et al.
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. [...]

Using radioactive beams to unravel local phenomena in ferroic and multiferroic materials / Schell, J (CERN ; Duisburg-Essen U.) ; Hofsäss, H (Gottingen U.) ; Lupascu, D C (Duisburg-Essen U.)
The increasing interest in using ferroic and multiferroic materials in high-tech applications requires that the underlying physical phenomena are studied at the atomic scale. Time-differential perturbed angular correlation (TDPAC) measurements have a local character and can provide important information concerning combined magnetic dipole and electric quadrupole interactions in multiferroic systems.

Multiferroic bismuth ferrite: Perturbed angular correlation studies on its ferroic $\alpha$-$\beta$ phase transition / Marschick, G (Vienna, Tech. U. ; CERN) ; Schell, J (CERN ; U. Duisburg-Essen) ; Stöger, B (Vienna, Tech. U.) ; Gonçalves, J N (Aveiro U.) ; Karabasov, M O (U. Duisburg-Essen) ; Zyabkin, D (Ilmenau Tech. U.) ; Welker, A (CERN) ; Escobar C , M (U. Duisburg-Essen) ; Gärtner, D (Munster U.) ; Efe, I (Zurich, ETH) et al.
Work of numerous research groups has shown different outcomes of studies of the transition from the ferroelectric $\alpha$-phase to the high temperature $\beta$-phase of the multiferroic, magnetoelectric perovskite Bismuth Ferrite (BiFeO$_{3}$ or BFO). Using the perturbed angular correlation (PAC) method with $^{111m}$Cd as the probe nucleus, the $\alpha$ to $\beta$ phase transition was characterized. [...]

Incorporation of Cd-Doping in SnO$_2$ / Schell, J (CERN ; Duisburg-Essen U.) ; Dang, T T (Bonn U., HISKP) ; Carbonari, A W (IPEN, Sao Paulo)
Tuning the electrical properties of materials by controlling their doping content has been utilized for decades in semiconducting oxides. Here, an atomistic view is successfully employed to obtain local information on the charge distribution and point defects in Cd-doped SnO$_2$. [...]

The Local Exploration of Magnetic Field Effects in Semiconductors / Dang, Thien Thanh (Duisburg-Essen U.) ; Schell, Juliana (Duisburg-Essen U. ; CERN) ; Beck, Reinhard (Bonn U.) ; Noll, Cornelia (Bonn U.) ; Lupascu, Doru C (Duisburg-Essen U.)
This study reports on the local exploration of magnetic field effects in semiconductors, including silicon (Si), germanium (Ge), gallium arsenide (GaAs), and indium phosphide (InP) using the time differential perturbed angular correlation (TDPAC) technique. TDPAC measurements were carried out under external magnetic fields with strengths of 0.48 T and 2.1 T at room temperature, and 77 K following the implantation of 111In (111Cd) probes. [...]

Perturbed Angular Correlation Technique at ISOLDE/CERN Applied for Studies of Hydrogenated Titanium Dioxide (TiO2): Observation of Cd-H Pairs / Zyabkin, Dmitry V (Ilmenau Tech. U.) ; Schell, Juliana (CERN ; Duisburg-Essen U.) ; Correia, João G M (CERN ; IST/ITN, Lisbon) ; Vetter, Ulrich (Ilmenau Tech. U.) ; Schaaf, Peter (Ilmenau Tech. U.)
Profound understanding of the local electronic and defect structure in semiconductors always plays a vital role in the further developing of applications of such materials. In the present work an investigation of the electronic structure in hydrogenated TiO2 (rutile) thin films is conducted by virtue of Time-Differential γ-γ Perturbed Angular Correlation spectroscopy (TDPAC or PAC) with 111mCd/Cd isotope, produced and implanted at ISOLDE/CERN.

Strong magnetoelectric coupling at an atomic nonmagnetic electromagnetic probe in bismuth ferrite / Schell, Juliana (CERN ; Duisburg-Essen U.) ; Schmuck, Merlin (Duisburg-Essen U.) ; Efe, İpek (Zurich, ETH) ; Dang, Thien Thanh (Duisburg-Essen U.) ; Gonçalves, João Nuno (Aveiro U.) ; Lewin, Daniil (Duisburg-Essen U.) ; Castillo, Marianela Escobar (Duisburg-Essen U.) ; Shvartsman, Vladimir V (Duisburg-Essen U.) ; Costa, Ângelo Rafael Granadeiro (CERN ; Lisbon, IST) ; Köster, Ulli (Laue-Langevin Inst.) et al.
Isolated nonmagnetic substitutional defect ions experience huge coupled electric magnetic interaction in the single-phase multiferroic BiFeO$_{3}$. In the ferroelectric state above the magnetic Néel temperature $T$$_{N}$, the electric environment generates a single symmetric electric field gradient (EFG) parallel to the electric polarization direction.
