摘要：

We report observations of avalanchelike, topological rearrangements of cellular domain patterns in magnetic garnet films. Over significant intervals in applied magnetic field and cell density, the patterns self-organize into barely stable states. Small field increments trigger avalanches of cell destruction that span more than 2 orders of magnitude in size and lifetime. © 1990 The American Physical Society.
