摘要
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.
