Electrospinning provides a promising route to quickly produce high‐purity ceramic fibers from readily available sol–gel precursors. Recently, techniques have been developed to enable the production of biphasic nanocomposites on a single fiber, enabling the development of novel composites with connectivities that are difficult to obtain using existing methods. These “composites on a fiber” can be used as a unique anisotropic building block for creating more complex ordered structures. This work examines links between processing, structure, and properties for Janus‐type composite nanofibers for the magnetoelectric BaTiO 3 – CoFe 2 O 4 system. Specifically, we show how altering the viscosity and conductivity of precursor solutions can provide a unique route to synthesize biphasic composites of a range of sizes and compositions. Furthermore, we show how altering these properties can impact the magnetic and magnetoelectric behavior of these fibers. While this work focuses specifically on the BaTiO 3 ‐ CoFe 2 O 4 system, lessons learned can be applied to electrospinning biphasic ceramic materials from a variety of material systems and applications.
