n.反铁磁性
In this paper, we are mainly interested in the spin reorientation transition in antiferromagnetism. 本文将采用二维正方格子的海森伯格模型Hamiltonian，利用自洽的量子平均场方法来讨论低维反铁磁体系中的自旋构型转变。
As Mn concentration increases, the magnetic properties transform from FM to antiferromagnetism (AF). 随着Mn含量继续增大，薄膜的磁性从铁磁性转变成为反铁磁性。
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. 通过对铁磁共振线的强度、线宽和共振场与温度依赖关系的讨论，我们得出T(下标M2)附近的峰对应着体系的反铁磁转变。
