Oxide self-assembly is a promising bottom-up approach for fabricating new composite materials at: the nanometer length scale. Tailoring the properties of such systems for a wide range of electronic applications depends on the fundamental understanding of the interfaces between the constituent phases. We show that the nanoscale strain modulation in self-assembled systems made of high-T-c superconducting films containing nanocolumns of BaZrO3 strongly affects the oxygen composition of the superconductor. Our findings explain the observed reduction of the superconducting critical temperature.
