铁电畴、铁弹性畴或铁磁畴的厚度和形状的标准“基特尔定律”假定力学平衡。本文表明，这些区域可能是高度不平衡的，具有不同寻常的厚度和形状。在锗酸铅和多铁锆钛酸铅中，钽酸铁畴壁的不稳定性类似于流体动力学（分别为richmyer - meshkov和hellich - hurault）。
The standard “Kittel Law” for the thickness and shape of ferroelectric, ferroelastic, or ferromagnet domains assumes mechanical equilibrium. The present paper shows that such domains may be highly nonequilibrium, with unusual thicknesses and shapes. In lead germanate and multiferroic lead zirconate titanate iron tantalate domain wall instabilities resemble hydrodynamics (Richtmyer–Meshkov and Helfrich–Hurault, respectively).
