We experimentally investigate terahertz pulse transmission through dense, random ensembles of sub-wavelength ferromagnetic Co particles. Due to the magnetoresistance inherent to the ferromagnetic metal, the terahertz optical properties of the Co particle ensembles are shown to be strongly dependent on the strength and orientation of an external magnetic field.
