dc.description.abstract | Porous silicon PS matrices with oriented, separated pores grown perpendicular to the surface are used as a template for the
incorporation of magnetite nanoparticles. The Fe3O4 particles used for infiltration into the PS template are coated with oleic acid
in a hexane solution and exhibit an average diameter of 8 1.5 nm. The narrow size distribution and the superparamagnetic
behavior at room temperature are interesting features of these nanoparticles. In addition, the use of PS as a template for the particle
deposition influences and modifies the collective magnetic response of the nanoparticles. Especially, anisotropy between the two
magnetization directions, magnetic field parallel and perpendicular to the surface, has been observed. Magnetite nanoparticles play
a key role in medical applications, but also the magnetic properties of such a nanoparticle/PS system are of technical interest due
to the transition between superparamagnetic and ferromagnetic behaviors. Temperature-dependent magnetization measurements
are used to gain information about the magnetic interaction of the particles. | en |
