Abstract

We report the first observation of Faraday rotation of light in multiple-scattering media. Speckle patterns generated by diffusive transport of laser light through turbid granular samples are strongly modified by high magnetic fields ( B ). The speckle intensity correlation function, measured at various sample thicknesses and Verdet constants, decays with increasing B in agreement with the simple model discussed. In addition the coherent backscattering cone is partially suppressed by the field, again consistent with the model. This effect provides a unique way to destroy interferences between time-reversed scattering paths and may be expected to affect light localization.
