Oblique-incidence (45 degrees) FeF2 for infrared reflectivity data in
both polarisations are reported for several relative orientations of t
he static field H-0 and the c axis. For c along H-0 we observe the AF
resonance line, its Zeeman splitting and nonreciprocal reflectivity R(
-H-0)not equal R(H-0). For c transverse to H-0 s and p resonances are
different.
