Although no net magnetization is generated in these A-type antiferromagnetisms, the FE polarization can create a layer-dependent electrostatic potential, which makes electronic bands in different layers stagger, producing spin splitting. Moreover, the spontaneous spin-splitting in FE A-type ...

·奈尔(Louis Néel)因对反铁磁的预测和开创性研究获得了1970年的诺贝尔物理学奖. 反铁磁性(antiferromagnetism)的发现补充了之前已知的几种磁性类型——抗磁性(diamagnetism)、顺磁性(paramagnetism)和铁磁性(ferromagnetism), 共同构成当今我们对磁性材料理解的基础框架. 上述对磁性材料的分类是建立在相邻磁矩共线排列的...

Effects of Oxygen Content on Bi3Mn3O11+δ: From 45 K Antiferromagnetism to Room-Temperature True Ferromagnetism The effects of oxygen content on the structural, physical, and chemical properties of Bi(3)Mn(3)O(11) with KSbO(3)-type structure have been investigated. I... AA Belik,E Takay...
Other transition metallic elements originally exhibit ferromagnetism so that no large differences exist between antiferromagnetism and ferromagnetism, but the ferromagnetic states may be similarly varied and the ferromagnetic transition temperatures may by adjusted. It should be noted that unlike the above ...
Competition between ferromagnetism and antiferromagnetism in FePt The large anisotropy of L1FePt and the ability to synthesize it as nanoparticles make it an ideal candidate for future recording media. Many first-principl... G Brown,B Kraczek,A Janotti,... - 《Physical Review B》 被引量: 92...
研究表明,铌钽在低温下(低于它的居里温度)存在反铁磁性(antiferromagnetism)行为。具体来说,当外磁场加强时,铌钽中的磁矩也会随之增强,但是当外磁场达到一定阈值时,铌钽中的磁矩会发生翻转,即从非磁性状转变为磁性状,这种行为被称为“相变”。 总结:尽管铌钽本身不具备磁性,但是其磁学性质及其在外磁场中的行为...
We propose a mechanism for A-type antiferromagnetism in orthorombic LaMnO_3,\ncompatible with the large Jahn-Teller splitting inferred from structural data.\nOrbital ordering resulting from Jahn-Teller distortions effectively leads to\nA-type ordering (antiferromagnetic in the c axis and ferromagnetic...
The antiferromagnetism of the oxidized ferrocene-based ladderphanes further indicates strong coupling between linkers in these ladderphanes. These polynorbornene-based ladderphanes can easily aggregate to form a two-dimensional, highly ordered array on the graphite surface with areas that can reach the ...
