摘要
详细推导了液晶材料在磁场中的磁化率各向异性Δχ、磁化强度M以及磁场强度H的张量表达式,在此基础上推导了液晶与磁场的相互作用能的定量关系表达式,发现当Δχ、H的值增加时或者指向矢n与H的夹角减小时,液晶与磁场的相互作用能增加。
In this paper the magnetic susceptibility anisotropic Δχ, magnetization and magnetic flux density of liquid crystal is deduced carefully. Then the interaction energy between liquid crystal and magnetic field is given and it can be found that the interaction energy will be increased, when Δχ, is increased or the angle between order parameter and is decreased.
