Various NiFe\u2010based nanowire and nanotube structures have been made via lithography patterning methods for magnonics demonstration. In this work, through the concept of self\u2010assembled vertically aligned nanocomposite (VANs) thin films, vertically aligned NiFe (80:20) nanopillars are uniformly grown into an insulating dielectric oxide matrix (CeO\n                    <jats:sub>2<\/jats:sub>\n                    ) as a hybrid metamaterial framework for nanoscale magnonics demonstration.
