摘要：

The behavior of the domain structure in a two-layer iron garnet film in a bias field was examined visually. The experiment was conducted at T approximately equals T(comp) equals 312 K, corresponding to the compensation temperature of the upper film. Models are proposed for the magnetic states of a two-layer film, which account for the observed features of the film magnetization process. In a bias field H approximately equals 300 Oe, an orientational first-order phase transition occurs because of the presence of a unidirectional exchange anisotropy which is qualitatively different in nature from those described previously and offers promise of technological applications.
