%X ABSTRACT Bi2WO6:CoFe2O4 (BWO:CFO) vertically aligned nanocomposite (VAN) in epitaxial thin film form has been demonstrated on single-crystal LaAlO3 (LAO) (001) substrates via pulsed laser deposition (PLD). CFO nanopillars exhibit a unique nanocone shape embedded in the epitaxial BWO matrix with an Aurivillius layered oxide structure. The growth direction of the CFO nanopillars is (004), different from that of its epitaxial single-phase counterpart (220), which is attributed to the interfacial strain effect. Magnetic measurements show robust and anisotropic magnetic properties from the CFO nanocone structures, and obvious ferroelectric responses are demonstrated in the BWO matrix, both at room temperature. GRAPHICAL ABSTRACT IMPACT STATEMENT The BWO:CFO VAN thin film combining a ferroelectric layered oxide matrix and magnetic vertical nanocone present a new hybrid material platform for room temperature multiferroics design towards nanoscale sensors and actuators
