Abstract

We demonstrated selective fluorination of a SrFeO_2.5 layer in a SrFeO_2.5/SrRuO₃ epitaxial bilayer film via a topotactic reaction with polyvinylidene difluoride while maintaining the epitaxial relationship. Physical property measurements of the SrFeO₂F/SrRuO₃ heterostructure confirmed that the SrRuO₃ layer could work as a good bottom electrode.
