Diamagnetic susceptibility of liquids is studied by investigating field induced magnetic birefringence with high sensitivity under pulsed high magnetic field. In this research project, we found, for the first time, that the "Curie-Weiss Law" of diamagnetic susceptibility is generally applicable to the usual organic liquids. Curie-Weiss constants, which reflect the molecular interactions in the liquids, are obtained for various organic liquids.The binary mixtures of liquids are also investigated and theoretical analysis based on the mean field theory predicts well the experimental results. However, binary mixtures of carbon tetrachloride with aromatic liquids show curious characteristics difficult to be explained by the mean field theory. By careful examination of the diamagnetic susceptibility, cluster model is proposed for the mixture where the cluster is composed of one carbon-tetrachloride molecule and surrounding several aromatic molecules.Anisotropic diamagnetic susceptibilities of molecules are revised by this research using newly obtained Curie-Weiss law.

通过研究脉冲强磁场下高灵敏度的场致磁双折射来研究液体的抗磁磁化率。在本研究项目中，我们首次发现，反磁化率的“居里-外斯定律”普遍适用于通常的有机液体。对各种有机液体进行了Curie-Weiss常数的计算，得到了反映液体中分子间相互作用的Curie-Weiss常数，并对二元混合液体进行了研究，基于平均场理论的理论分析与实验结果吻合较好。然而，四氯化碳与芳香族液体的二元混合物显示出难以用平均场理论解释的奇怪特性。通过对反磁化率的研究，提出了由四氯化碳分子和多个芳烃分子组成的团簇模型，并利用Curie-Weiss定律修正了分子的各向异性反磁化率.
