dc.description.abstractPerovskite/spinel nanocomposites have attracted great attention due to the novel properties that originate from the coupling between two oxides through their interfaces. Combinatorial pulsed laser deposition was used in this work to grow La0.8Sr0.2CoO3 (LSC)/CoFe2O4 (CFO) nanocomposites on (001) SrTiO3 (STO) under various growth conditions. At a substrate temperature of 680 degrees C, the LSC/CFO consisted of columns of CFO and a third phase, likely to be CoOx, within a highly textured LSC matrix. Lowering the temperature to 600 degrees C resulted in highly textured LSC/CFO nanocomposites consisting of grains of LSC and CFO a few nanometers in diameter. The grain size increased with decreasing growth rate. In the nanocomposites, redistribution of Fe into the perovskite phase is expected. The strain in the CFO was impacted by the lattice match at the interfaces with the LSC, and changes in composition as well as the strain led to lower magnetic anisotropy compared with CFO films on STO. This approach can also be used to produce other novel nanocrystalline spinel/perovskite systems-
