In this paper, we demonstrate the capability of growing two alternative complex oxides with different stoichiometries and crystal structures, by choosing the appropriate substrate and adjusting the target ablation ratio, and tuning their composition and properties by combinatorial pulsed-laser ablation of their precursors. In particular, we successfully grew epitaxial crystalline yttrium iron garnet (Y3Fe5O12) on yttrium aluminium garnet (Y3Al5O12) substrates and polycrystalline yttrium ferrite (YFeO3) on sapphire (α-Al2O3) substrates by co-ablation of yttrium oxide and iron oxide targets.
