Protonic and electronic defects in the 12R-type hexagonal perovskite Sr3LaNb3O12

The structural properties of the 12R-type hexagonal perovskite Sr3LaNb3O12 (space group R3¯) have been examined by neutron diffraction and 1H magic angle spinning-nuclear magnetic resonance (1H MAS–NMR). The latter technique supports the presence of protonic species in Sr3LaNb3O12 with bands at 5, 3...
