论文摘要
具有损坏的极性对称性的鸟类是软物质领域中最令人着迷的发现之一。高自发极化和铁电列$ n _ {\ mathrm {f}} $相位的流动性使此类材料对未来的应用有吸引力，并且对基本研究很有趣。在这里，我们探讨了室温铁电列及其在磁场中的行为的极性和机械性能。我们表明，$ n _ {\ mathrm {f}} $比扭曲的易感性要小得多。强烈的僵硬刚度可以归因于极化的静电自相互作用，避免了极化的震动。
Nematics with a broken polar symmetry is one of the fascinating recent discoveries in the field of soft matter. High spontaneous polarisation and the fluidity of the ferroelectric nematic $N_{\mathrm{F}}$ phase make such materials attractive for future applications and interesting for fundamental research. Here we explore the polar and mechanical properties of a room-temperature ferroelectric nematic and its behaviour in a magnetic field. We show that $N_{\mathrm{F}}$ is much less susceptible to the splay deformation than to the twist. The strong splay rigidity can be attributed to the electrostatic self-interaction of the polarisation avoiding the polarisation splay.
