[求助]
求助帖。到底什么是G型反铁磁 已有1人参与
|
| 文献上一直讲铁酸铋是G型反铁磁，同时具有一个62nm的螺旋自旋调制结构。想求助一下各位科研前辈反铁磁到底是怎么分类为A、B、C、G型的。翻了很多磁学的书还是没找到，很是苦恼。求前辈们指条明路，讲讲也好，共享点资料也好，拜谢 |

a collinear bipartite antiferromagnet composed of two interpenetrating square lattices A and B possessing antiferromagnetically aligned moments [see Fig. 1(a), the extension to three dimensions is straightforward]. This configuration is usually referred to as a G-type or checkerboard antiferromagnet, i.e.,when both intraplane and interplane couplings are antiferromagnetic (other collinear bipartite spin structures exist, such as the A-type structure when intraplane coupling is ferromagnetic and inter lane coupling is antiferromagnetic, or the C-type structure when intraplane coupling is antiferromagnetic and interplane coupling is ferromagnetic.) 文献上看到的，翻译一下就是：G型是面内和平面间耦合都是反铁磁性；A型是面内耦合是铁磁性，平面间耦合是反铁磁；C型是面内耦合是反铁磁性，平面间耦合是铁磁性。 |
