Abstract

Mesoporous silicon is utilized to infiltrate quite monodisperse iron oxide nanoparticles into the pores. This semiconducting matrix exhibits oriented pores, clearly separated from each other, with an average pore diameter of 55 nm. Iron oxide nanoparticles of 8 nm and 5 nm in size which are coated with a surfactant are prepared by high temperature decomposition in the presence of an organic precursor. The achieved nanocomposite consists of dispersed Fe3O4-nanoparticles within the pores and offers magnetic properties which are determined by the morphology of the silicon matrix as well as by the distribution of the particles within the individual pores. Thus, the change of regime between a superparamagnetic and a blocked state of the system can be tuned. Furthermore, magnetic anisotropy between the two magnetization directions, normal and parallel to the sample surface, is observed due to the oriented and separated pores of the template which are quasi-regular arranged. This porous silicon/magnetite composite with its adjustable magnetic properties is also of interest for possible applications in biomedicine due to the low toxicity of both materials.
