Abstract

Nanocrystalline LiFe₅O₈ particles of several nanometers in size have been prepared by the PEG gel method, their particle structure, morphology and magnetic properties were examined by XRD, TEM and VSM. It was found that σ_s/σ_bulk decreases with decreasing particle size, where σ_s is the saturation magnetization. The surface effect is probably the dominant effect in the decrease of σ_s. The Curie temperature of LiFe₅O₈ (9.1 nm in diameter) decreased to 580°C which is lower than that of bulk LiFe₅O₈ (620°C).
