MnTe中的交变磁性:起源、预测表现及去孪晶化途径

Altermagnetism in MnTe: origin, predicted manifestations, and routes to detwinning

I. I. Mazin

AI总结:

本文研究MnTe中交变磁性的起源,提出利用其特殊磁序制备去孪晶样品,并通过第一性原理计算预测可观测的磁光响应作为交变磁性的标志。

摘要:

MnTe最近作为交变磁性候选材料受到关注。实验上,它具有铁磁性ab面沿c轴反铁磁堆叠的交变磁序。我们表明,这种磁序(本身并非平凡,因为面内交换是反铁磁性的)开启了制备交变磁性去孪晶样品的有趣可能性,并产生可观测的磁光响应(我们从第一性原理计算得出),作为交变磁性的特征。

英文摘要:

MnTe has recently attracted attention as an altermagnetic candidate. Experimentally it has an altermagnetic order of ferromagnetic $ab$ planes, stacked antiferromagnetically along $c$. We show that this magnetic order (by itself non-trivial, since the in-plane exchange in antiferromagnetic) opens intriguing possibility of manufacturing altermagnetically-detwinned samples and generate observable magnetooptical response (which we calculate from first principles) as a signature of altermagnetism.
