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...
铌钽在外磁场中的响应行为也是研究的重点。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...

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 ...

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 ...
