Project Area CC4: Identifying Composition-Processing-Defect- Structure-Property Correlations in Continuous (La-Sr-)Fe-Co-O Thin Film Composition Spreads

Project C4 investigates CRC/TRR’s prototype mixed metal oxide systems using continuous composition spread thin films (CCS) where materials with well-defined composition gradients are synthesised by combined reactive sputtering and thermal treatment.
