Sol-gel route to prepare well-ordered nanowires with anodic aluminum oxide template

摘要

In this work, we report a sol-gel route to fabricate oxide nanowires of BiFeO3 using two-step anodic aluminum oxide as template. We prepared oxide nanowires with uniform dimensions that can vary from 35 to 100 nm in diameter and with 4 urn in length, as confirmed by scanning electron microscopy and transmission electron microscopy measurements. Magnetization measurements, performed in a vibrating sample magnetometer, show that this nanostructures present ferromagnetism at room temperature.
