Magnetic composite nanoparticles containing iron and mullite were prepared by reduction of sol-gel-made mullite-iron oxide solid solution. The magnetic properties of nanocomposite suggest that a part of the iron particle exists in the superparamagnetic state. TEM observation shows that metal nanoparticles have an intragranular distribution with iron embedded in mullite grains.
