Crafting the multiferroic BiFeO₃-CoFe₂O₄ nanocomposite for next-generation devices: A review

BiFeO3-CoFe2O4 (BFO-CFO) vertically aligned nanocomposite (VAN) thin-film promises great potentials for next-generation electronic devices. Its strong magnetoelectric, antiferromagnetic-ferrimagnetic, and structural couplings occur via large interface area interactions across the vertical surface between BFO CFO phases; this leads to emergent exotic fundamental physics rendering its potential applications various electronics, such as magnetic sensor, data storages or memory devices, energy harvesting The distinctive photoactivity of both phases in BFO-CFO VAN system also can generate advanced photovoltaic photocatalytic Furthermore, owing small overpotential excellent stability alkaline media, nanocomposites becomes next electrode electrocatalysis have been exponentially developed having type architectures grown on substrates. In present article, we review current status discuss understanding well technology involved developing material. We address challenges that hinder commercialization material propose some plausible solutions encourage VAN-based devices reach their maturity level. marketability materials future consumer products is discussed.
