NanoSIMS analysis of Ca doping at a grain boundary in a superconducting YBCO Ca-123/123 bicrystal
Calcium doping is well known to increase the grain boundary critical current, Jcgb, in polycrystalline Y1Ba 2Cu3O7-δ, (YBCO). High resolution Secondary Ion Mass Spectroscopy (nanoSIMS) analysis has been used to map the distribution of Ca+ ions in three dimensions in an YBCO grain boundary grown on a...
