| 摘 要： | 我们发展了处理低温下铁磁和反铁磁运动学相互作用的一个新方法。所有运动学相互作用都能用各级关联函数来表示。应用热力学微扰理论,导得低温下s=1/2的铁磁体系的确没有T3项。对反铁磁体系,我们发现运动学相互作用即使在低温下也十分大,它甚至超过动力学相互作用的修正,我们的理论适用于s≥1/2的一切体系。

| Abstract: | A new method is developed to treat the ferromagnetic and the antiferromagnetic kinematic interactions. All the kinematic interactions can be represented by means of every order correlation functions. It is shown that the ferromagnetic system (s=1/2) does not involve the T3-term at low temperature. For the antiferromagnetic system, we find that the kinematic interaction is large than the dynamic interaction even at low temperature. Our theory is good for all spin values s as well. |
