Abstract

Uniformly dispersed amorphous nanoparticles of magnetite in polyvinyl alcohol have been obtained by ultrasound radiation. The properties of the as-prepared composite material were characterized by various analytical methods. We have found that the magnetite particles that were 12–20 nm in diameter were very well dispersed in the PVA. The magnetization measurements establish that the composite material is superparamagnetic in nature.
