n.反鐵磁性

In this paper, we are mainly interested in the spin reorientation transition in antiferromagnetism. 本文將采用二維正方格子的海森伯格模型Hamiltonian，利用自洽的量子平均場方法來討論低維反鐵磁體系中的自旋構(gòu)型轉(zhuǎn)變。

As Mn concentration increases, the magnetic properties transform from FM to antiferromagnetism (AF). 隨著Mn含量繼續(xù)增大，薄膜的磁性從鐵磁性轉(zhuǎn)變成為反鐵磁性。

According to the results of the temperature dependencies of the intensity, linewidth and resonance field, we conclude that the peak at T(subscript M2) is a transition of antiferromagnetism. 通過對鐵磁共振線的強(qiáng)度、線寬和共振場與溫度依賴關(guān)系的討論，我們得出T(下標(biāo)M2)附近的峰對應(yīng)著體系的反鐵磁轉(zhuǎn)變。
