Spin-polarized antiferromagnets have recently gained significant interest because they combine the advantages of both ferromagnets (spin polarization) and antiferromagnets (absence of net magnetization) for spintronics applications. In particular, spin-polarized antiferromagnetic metals can be useful as active spintronics materials because of their high electrical and thermal conductivities and their ability to host strong interactions between charge transport and magnetic spin textures. We review spin and charge transport phenomena in spin-polarized antiferromagnetic metals in which the interplay of metallic conductivity and spin-split bands offers novel practical applications and new fundamental insights into antiferromagnetism. We focus on three types of antiferromagnets: canted antiferromagnets, noncollinear antiferromagnets, and collinear altermagnets. We also discuss how the investigation of spin-polarized antiferromagnetic metals can open doors to future research directions.

自旋极化反铁磁金属


自旋极化反铁磁体最近引起了人们的极大兴趣，因为它们结合了铁磁体（自旋极化）和反铁磁体（无净磁化）的优点，可用于自旋电子学应用。特别是，自旋极化反铁磁性金属可用作活性自旋电子学材料，因为它们具有高导电性和导热性，并且能够承载电荷传输和磁性自旋纹理之间的强相互作用。我们回顾了自旋极化反铁磁性金属中的自旋和电荷传输现象，其中金属电导率和自旋分裂带的相互作用为反铁磁性提供了新的实际应用和新的基本见解。我们重点介绍三种类型的反铁磁体：倾斜反铁磁体、非共线反铁磁体和共线交替磁体。我们还讨论了自旋极化反铁磁金属的研究如何为未来的研究方向打开大门。
