Abstract

We have developed a new method to fabricate extremely small transition-metal oxide nanowires. Using a combination of nanoimprint template patterning and inclined substrate pulsed laser deposition, we successfully fabricated magnetic oxide Fe _2.5Mn _0.5O ₄ nanowall-wires, and controlled the width in a range from 120nm down to about 20nm by varying deposition parameters. Magnetoresistance measurements revealed ferromagnetic properties of the Fe _2.5Mn _0.5O ₄ nanowall-wire. This method enables the study of mesoscopic transport properties of transition-metal oxides towards the development of oxide-based nanodevices.
