, in the absence or presence of a magnetic field oriented along (or slightly off) one of the major crystallographic axes, are given in detail for the first time. We present a simple model to simulate the profiles of exchange induced exciton-magnon combination bands in canted ferromagnets, under various experimental conditions of temperature and magnetic field. This model is used to analyse new high-resolution magneto-optical data at low and very low (0.35 K) temperatures and to derive precise anisotropy parameters. It can be applied with only slight modifications to metamagnets showing axial or planar anisotropy.
