[求助]
求助帖。到底什么是G型反鐵磁 已有1人參與
|
| 文獻上一直講鐵酸鉍是G型反鐵磁,同時具有一個62nm的螺旋自旋調(diào)制結(jié)構(gòu)。想求助一下各位科研前輩反鐵磁到底是怎么分類為A、B、C、G型的。翻了很多磁學的書還是沒找到,很是苦惱。求前輩們指條明路,講講也好,共享點資料也好,拜謝 |

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.) 文獻上看到的,翻譯一下就是:G型是面內(nèi)和平面間耦合都是反鐵磁性;A型是面內(nèi)耦合是鐵磁性,平面間耦合是反鐵磁;C型是面內(nèi)耦合是反鐵磁性,平面間耦合是鐵磁性。 |
