Heisenberg의 强磁性 및 反强磁性에 關한 Green函數 硏究
Abstract
Heisenberg의 强磁性 反强磁性에 대한 統一된 Green 函數理論을 수립하였다.

Green 函數의 運動方程式을 Callen의 decoupling 近似方法으로 分離시켜서 解를 求하고 이 解를 利用하여 强磁性에 대한 Curie 溫度 및 그 上下에서 spin의 橫的相關函數를 計算하였다. 이 結果가 다른 硏究結果와 一致하였다.
The unified Green function theory is developed for the Heisenberg ferro-and antiferro-magnets. The equation of motion for the Green function is decoupled by the Callen decoupling approximation. The Solution of the equation is used to find the transverse corrlation functions of spins at, above, and below the Curie temperature for the ferromagnets. The results are found to be consistent with the others.
