Аннотация: Self-organisation in iron garnet films that are perspective optoelectronics materials is studied in this paper. We present results of research of dynamic domain structures formation, growth and destruction in $(YLuBi)_3(FeGa)_5O_12$ iron garnet film (111) with perpendicular magnetic anisotropy (quality factor $Q = 73$). The sample was studied in a temperature range of $77\div 300$ K in a sinusoidal magnetic field oriented perpendicular to its surface ($f = 0.06\div 5$ kHz, $H_0$ up to 100 Oe). Dynamic domain structures were visualized by means of magneto-optical Faraday effect. Main stages of spiral domain formation were established. Dependencies of spiral domain radius during its formation, growth and destruction on time were obtained.
