用光学技术研究了掺杂不同大小磁性颗粒的CoFe2O4离子磁流体的溶致液晶。确定了取向液晶所需的最小颗粒浓度。Brochard和De Gennes的磁悬浮理论被推广到包括椭圆形颗粒。
A lyotropic liquid crystal doped with CoFe2O4ionic ferrofluid with magnetic grains of different sizes is studied by means of optical techniques. The minimum concentrations of grains required to orient liquid crystals are determined. Brochard's and de Gennes' theory of magnetic suspensions is extended to include ellipsoidal grains.
