摘要： Temperature dependence of magnetic anisotropy of homologous nematic fluorinated phenyl bicyclohexane liquid crystals is measured by a magneto-electric method. The result shows that the diamagnetic property is slightly influenced by the positions and the numbers of fluorine atoms substituted at the phenyl ring. By investigating the correlation of the dielectric anisotropy with the magnetic anisotropy, a novel explanation is proposed for the behaviour of the molecular dipole—dipole dimerization in the polar liquid crystal compounds.
