磁性材料在激光优化时自旋—自旋耦合的影响

THE INFLUENCE O FMAGNETIC MATERIAL OPTIMIZED BY LAZER ON S-S COUPLING

本文针对磁性材料在激光优化时，其自旋──自旋耦合进行了研究，应用外斯分子场理论推导出磁化强度与自旋耦合的交换积分的反比关系。进而从理论上进一步证实磁性材料自旋取向有趋平行的变化趋势。

In this paper the research is made on the s-s coupling of magnetic material in its optimization by laser.The relation in inverse proportion between magnetization and the exchange intergral of s-s coupling is derived by using Welss Molecular Physical Theory,thus proving further in theory that there is a tendency that spins orienta-tion of magnetic material varies in paralled .
