The formation of flexoelectric stripe patterns (flexodomains) was studied under the influence of external electric and magnetic fields in a nematic liquid crystal. The critical voltage and wavevector of flexodomains were investigated in different geometries by both experiments and simulations. It is demonstrated that upon altering the orientation of the magnetic field with respect to the director, the critical voltage and wavenumber behave substantially differently. In the geometry of the twist Freedericksz transition, a non-monotonic behavior as a function of the magnetic field was found.
在向列型液晶中，研究了外部电场和磁场影响下挠曲电条纹图案（挠曲畴）的形成。通过实验和模拟研究了不同几何结构中挠曲畴的临界电压和波矢。结果表明，改变磁场相对于指向矢的方向时，临界电压和波数的表现有很大不同。在扭曲弗雷德里克兹转变的几何结构中，发现了作为磁场函数的非单调行为。
