Integration of functional thin films with a multiferroic property on flexible substrates has piqued tremendous research interest and device potential for flexible electronics. In this work, self-assembled BaTiO3–Fe vertically aligned nanocomposite (VAN) thin films have been integrated on mica substrates using pulsed laser deposition. Different buffer layers have been explored to facilitate VAN growth. The anisotropic ferromagnetic property and room temperature ferroelectric property have been achieved in the films. The bending test up to 1000 cycles signifies the mechanical stability of the physical properties. This work paves an avenue to integrate multiferroic oxide–metal nanocomposites for future flexible device integration.
