title = "Smart dust: Ferromagnetic photonic crystals derived from porous silicon",
abstract = "Micron-sized magnetic particles consisting of a porous Si photonic crystal with attached Fe nanoparticles are prepared. The photonic crystals are generated by electrochemically etching a porous multilayered dielectric mirror into silicon. The film is removed from the Si substrate and magnetic Fe nanoparticles are deposited on the mirror from a colloidal dispersion. The film is then fractured into small particles, yielding microscopic magnetic photonic crystals that are brightly colored on one side and dark black on the other. The magnetic porous silicon photonic crystals can be flipped between the colored side and the dark side by application of a small magnetic field. Switching of the particles at a rate of 175 Hz is demonstrated.",
