Epitaxially grown single‐crystal perovskite (100) three‐axis‐oriented (Ba 0.7 Sr 0.3 )TiO 3 thin films were prepared on a (100) platinum‐coated (100) magnesium oxide (MgO) single‐crystal substrate by the chemical solution deposition method using a solution derived from Ba(CH 3 COO) 2 , Sr(CH 3 COO) 2 , and Ti(O‐ i ‐C 3 H 7 ) 4 .The growth of the film was found to depend on the annealing condition. A (Ba,Sr)TiO 3 thin film annealed at 1073 K was found to be a single crystal by transmission electron microscope. The single‐crystal film exhibited a (100) three‐axis orientation that followed the (100) orientation of the Pt substrate, as observed from an X‐ray pole figure measurement and selected area electron diffraction patterns.
