| 摘 要： | 在外磁场中我们用量子理论方法计算了铁磁体、反铁磁、亚铁磁体的自旋波谱,并对自旋波的特点进行了讨论。我们发现亚铁磁体既有类似于反铁磁体的磁序特性,又有类似于铁磁体的波谱特性。

| Abstract: | In this paper,we get the spin wave spectrum of ferromagnet,antiferromagnet and ferrimagnetic crystal in the presence of external magnetic field by quantum method,and also discuss the characteristics of the spin wave spectrum.We find that the magnetic order of ferrimagnet is similar to that of antiferromagnet and that its spin spectrum is similar to that of ferromagnet. |
