The overall aim of this research programme is to use far infrared spectroscopy to investigate non-reciprocalbehaviour1 of coupled bulk and surface polaritons under an applied magnetic field in a selection of bulk and lowdimensional antiferromagnetic media. The materials of interest include bulk antiferromagnets like FeF2, thinfilms of metallic Cr, and rare earth elements such as Ho, together with superlattices fabricated from alternatelayers of these and other, non-magnetic, materials.
