有限厚度的单轴铁磁体在退磁力的作用下自发地分裂成平行的条纹状磁畴。在足够大的外加磁场中，发生向六边形或”气泡”相的转变。我们研究了这个系统的相图与使用的金兹伯格-朗道方法，我们调查的调制相位的二维顺序的位错的影响。
A uniaxial ferromagnet of finite thickness spontaneously breaks into parallel" striped" domains as a result of demagnetizing forces. In a sufficiently large applied magnetic field a transition takes place to a hexagonal or" bubble" phase. We study the phase diagram of this system with the use of a Ginzburg-Landau approach and we investigate the effects of dislocations on the two-dimensional order of the modulated phases.
