The Diffusion Kinetics of Ba Cations in Perovskite BaTiO${}_3$: A Combined Tracer Diffusion and Metadynamics Study

Sylvia Koerfer, Bianca Dißmann, Norman Schier +3

Tracer diffusion experiments and metadynamics (MtD) simulations were used to study the diffusion of Ba cations in the cubic phase of the perovskite oxide BaTiO${}_3$. ${}^{130}$BaTiO$_…
