Perturbed Angular Correlation Spectroscopy – A Tool for the Study of Defects and Diffusion at the Atomic Scale

“…24b, the damping factor λ is proportional to the HFI A number of studies have utilized an empirical analysis to study defect jump rates near probes. These include the observation of H jumps near Hf in yttrium, hafnium, and dysprosium hydrides [94,95,96], of H jumps near Cd in Si [97] and HfV 2 H x [98], of Cu jumps near Cd in Si [99], of rare-earth (R) vacancy jumps near Cd in R 1-x Ni 2 [75], and of oxygen vacancies in R 2 M 2 O 7 (R = Nd, Sm, Eu, and Gd; M = Zr and Hf) pyrochlores [100] and in CeO 2 [69]. Examples of how such an empirical analysis has been used to study the motion of the PAC probe itself include studies of Cd jump rates in -Mn [101], Pd 3 Ga 7 [102], Pt 3 Ga 7 [103], Al 11 R 3 (R = La, Ce, Pr) [104], and LaSn 3 [105].…”
