Abstract: Three-dimensional magnetic photonic crystals were fabricated from silica spheres containing magnetite nano-particles, assembled in a magnetic field. Transmission studies showed significant, sharp features in the magnetic circular dichroism and Faraday rotation, centred on the edge of the third photonic band gap (PBG), but five times narrower than the transmission band gap in absence of a magnetic field. Narrow ellipticity and rotation peaks were observed exactly at the PBG due to the birefringence of the three-dimensional crystal.
