摘要：

We have investigated magnetic polaritons propagating in FeF2 by high resolution far-infrared reflection and attenuated total reflection (ATR) spectroscopy. Highly non-reciprocal behaviour of the reflectivity, R, i.e. R(+H-0) not equal R(-H-0) is observed in an applied magnetic field H-0. The results have been used to determine the magnetic polariton dispersion curves. (C) 1998 Elsevier Science B.V. All rights reserved.
