摘要：

Nanosized magnetite particles embedded in polypyrrole matrix have been studied by Mossbauer and electron magnetic resonance spectroscopy. Comparison with as grown magnetite is made. Hyperfine fields distribution is determined and line shape of resonance curves are discussed in terms of composite structure, sizes and treatments.
