Abstract A new colloidal composite formed by specially synthesized dimethylphenyl ferrite particles and a nematic liquid crystal (LC) is presented. By applying a small magnetic field during polarizing optical microscopy observations, it was found that the magnetic moment of the synthesized ferrite is perpendicular to the director of the LC. The optical transmission of laser light across the ferronematic was investigated under magnetic field. The critical magnetic field corresponding to the Freedericksz transition was obtained and discussed according to the Burylov and Raikher theory.

磁场作用下新型接枝铁氧体颗粒/液晶复合材料

摘要 提出了一种由特殊合成的二甲基苯基铁氧体颗粒和向列液晶(LC)形成的新型胶体复合材料。通过在偏光光学显微镜观察过程中施加小磁场，发现合成铁氧体的磁矩垂直于 LC 的指向矢。在磁场下研究了激光穿过铁素体的光传输。根据 Burylov 和 Raikher 理论，获得并讨论了对应于 Freedericksz 跃迁的临界磁场。
