英文摘要
The porous particles of maghemite were prepared from iron phosphate particles by a novel method using alkaline solution, and then these were immersed in a solution containing Co. The Co adsorbed porous particles of maghemite showed superparamagnetic behavior. The superparamagnetic blocking temperature of these particles was increased by the annealing. In addition, the results of X-ray absorption spectroscopy measurements showed that the local structure around Co in the Co adsorbed porous particles after annealing is very similar to that of CoFe2O4. Consequently, Co in the Co adsorbed porous particles after annealing probably locates at the cation vacancy site of maghemite.
