Microstructural features and domain formation in (Ba,Sr) 2 TiSi 2 O 8 fresnoites

Wong, Chui Ling; Ferraris, Christiano; White, Timothy


The formation and co-existence of crystallographically modulated and non-modulated regions in (Ba,Sr)2TiSi2O8 fresnoites is reviewed, particularly the dependence on local composition. It is shown that perturbations of the average fresnoite structure, determined from appreciable single crystals, are in some cases better described as nanometric domain intergrowths where departures from ideal stoichiometry are characteristics of incommensuration, while modulation is absent from volumes that are...[Show more]
