Preparation of nanorods from monodisperse iron spinel nanoparticles

摘要

The invention relates to the field of magnetoelectric materials. In particular, the invention relates to a method for manufacturing a nanorod by filling alumina ("Al2O3") with monodisperse iron spinel nanoparticles, and the composite material can be used for magnetoelectric sensors. The invention aims to produce a magnetic nanorod by a new method of filling a nanohole ("template") with a magnetic nanoparticle. A bottle of 100mlOn the nanoporous carrier (Fig. 4), a solution containing CoFe2O4 nanoparticles dispersed in "hexane" is treated at a size of about 100 nanometers. Then, the bottle is placed on the permanent magnet with 0.5T magnetic field by the magnetic field applied by the magnet, so as to attract the magnetic nanoparticles into the hole of the template.
