Description	826-829 Two samples of nanoparticles of Co₀․₄Zn₀․₆Fe₂O₄ with the average particle sizes of 6 nm and 15 nm have been synthesized by chemical co-precipitation method and followed by heat treatment at 600ºC. The cubic spinel structure in single phase has been confirmed by X-ray diffraction. The lattice parameters are 8.39 Å and 8.41 Å, respectively. ⁵⁷Fe Mössbauer spectra were recorded at 300 K and 80 K. Both samples are resolved in two patterns corresponding to two crystalline sites. The Mössbauer spectra and hysteresis curves for the two samples recorded at 300 K show superparamagnetic behaviour. The analysis of Mössbauer spectra reveal that the intensity of Fe³⁺ ions on both sites is nearly the same which indicate that the Zn²⁺ occupies the octahedral site in these samples.
