The anisotropy tends to be large in these samples, and high fields and frequencies are extremely useful in characterizing these systems, enabling the observation of (anti)ferromagnetic modes that cannot be detected at low fields. The thin films that are usually studied in ferromagnetic resonance because of the (more) isotropic demagnetization field are also particularly well adapted for study in high-field quasi-optical spectrometers.
