Abstract
Using a ferrofluid of cobalt-zinc ferrite nanoparticles (Co0.8Zn0.2Fe2O4) coated with oleic acid and suspended in ethanol, we have fabricated a 2D photonic crystal (PC) by the application of an external magnetic field perpendicular to the plane of the ferrofluid. The 2D PC is made by rods of nanoparticles organized in a hexagonal structure. By means of the plane-wave expansion method, we studied its photonic band structure (PBS) which depends on the effective permittivity and on the area ratio of the liquid phase. Additionally, taking into account the Maxwell-Garnett theory, we calculated the effective permittivity of the rods. We have found that the effective refractive index of the ferrofluid increases with its magnetization. Using these results, we calculated the band structure of the photonic crystal at different applied magnetic fields, finding that the increase of the applied magnetic field shifts the band structure to lower frequencies with the appearance of more band gaps
Biography
Javier Lopez has completed his undergraduate and the M.S. in Physics at the age of 30 years in the Universidad del Valle-Colombia. Most of his career has been devoted to the research and development of the materials science. Currently, he is developing his doctoral research work in the nanomagnetism area, applied to the study of magnetic nanoparticles for applications in nanophotonics and optoelectronic devices. He joined the Thin Films Group in 2003 and the Excellent Center for New Materials in 2005. He has published several papers into internationals recognized journals. At present, the research lines of interest are: Nanomagnetism, nanoparticles, ferrofluids and photonic crystals.
