Abstract

Nanocrystalline MnFe₂O₄ particles with average particle diameters 50 nm and less were synthesized by using the oxidation method. The superparamagnetic behavior, which is influenced by the particle size, was controlled by varying the concentration of the oxidant. The Mössbauer spectrum showed only sextets corresponding to the A- and B-sites of the ferrite, when the particle size is larger than 50 nm. However, the appearance of superparamagnetic doublet was recorded for the manganese ferrite particles synthesized using higher concentration of oxidant. The saturation magnetization of the particles larger than 50 nm was almost equal to their bulk counter part.
