Integration of Self-Assembled BaZrO3-Co Vertically Aligned Nanocomposites on Mica Substrates toward Flexible Spintronics

Integrating functional thin films with anisotropic physical properties onto flexible substrates is of great interest for future flexible electronic applications. In this work, self-assembled BaZrO3(BZO)-Co vertically aligned nanocomposite thin films have been integrated onto flexible mica substrates using pulsed laser deposition. Microstructure characterization shows high-quality growth of Co nanopillars in the BZO matrix. Tunable, anisotropic ferromagnetic properties of the films have been achieved by controlling the film thickness and the aspect ratio of Co nanopillars. The bending stability tests have been carried out under different bending conditions and cyclic bending conditions to explore the physical property variation of the films. The successful integration of BZO-Co on mica substrates opens a way for future flexible spintronics and device integration.
