/ Gerami, Adeleh Mokhles (IPM, Tehran ; CERN) ; Heiniger-Schell, Juliana (CERN ; Duisburg-Essen U.) ; da Silva, E Lora (Porto U.) ; Costa, Messias S (Para U.) ; Costa, Cleidilane S (Para U.) ; Monteiro, João G (IST/ITN, Lisbon) ; Pires, José J (Lisbon, CFTP) ; Pereira, Daniela R (Lisbon, ISEL) ; Díaz-Guerra, Carlos (Madrid U.) ; Carbonari, Artur W (IPEN, Sao Paulo) et al.
Lamellar α-MoO3 crystals were implanted with low fluence of radioactive Cd111m ions at ISOLDE-CERN. Subsequently, we have probed the interaction of the Cd impurity in the lattice with native point defects, such as oxygen vacancies, as a function of annealing temperature using the time differential perturbed angular correlations nanoscopic technique.

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$_2$. [...]

Magnetic field at Ce impurities in La sites of La$_{0.5}$Ba$_{0.5}$MnO$_{3}$ double perovskites
/ Bosch-Santos, B (Sao Paulo U.) ; Nascimento, N M (Sao Paulo U.) ; Saiki, M (Sao Paulo U.) ; Correa, E L (Sao Paulo U.) ; Sales, T S N (Sao Paulo U.) ; Pereira, L F D (Sao Paulo U.) ; Cabrera-Pasca, G A (Para U.) ; Saxena, R N (Sao Paulo U.) ; Schell, J (Duisburg-Essen U. ; CERN) ; Carbonari, A W (Sao Paulo U.)
Due to its rich variety of electromagnetic properties, such as a colossal magnetoresistance, charge and orbital ordering, and metal-insulator transition, the magnetic behavior in La$_{0.5}$Ba$_{0.5}$MnO$_{3}$ double perovskite compounds has been investigated by several techniques, however more experimental data, especially from atomic resolution techniques, are still necessary to understand such complex behavior. In this paper, we have used a nuclear and short-range technique, the Perturbed Angular Correlation (PAC) spectroscopy, to investigate the magnetic hyperfine interaction at the $^{140}$Ce and $^{111}$Cd probe nuclei as impurities occupying La sites.

/ISOLDE
We present a study of TiO$_2$ single crystals from the point of view of the dopant atom that simultaneously behaves as the probing element. We used gamma-gamma time dependent perturbed angular correlations working with selected tracer elements ($^{111}$In/ $^{111}$Cd, $^{111m}$Cd/ $^{111}$Cd) together to investigate the different behavior of Cd and In dopants, particularly their interaction with point defects in the TiO$_2$ lattice.
