反铁磁半导体由于其在自旋电子学中的潜在应用而受到人们的广泛关注。使用自旋极化扫描隧道显微镜在矢量场中工作，我们映射的非共线反铁磁自旋结构的半导体六角FeSe表面上的原子尺度。该表面具有面内补偿Neel结构，第一性原理计算进一步证实了这一点。
Antiferromagnetic semiconductors gain increasing interest due to their possible application in spintronics. Using spin polarized scanning tunneling microscopy operating in a vector field, we mapped the noncollinear antiferromagnetic spin structure of a semiconducting hexagonal FeSe surface on the atomic scale. The surface possesses an in-plane compensated Neel structure which is further confirmed by first-principles calculations.
