论文摘要
我们表明，基于“抗手术”秩序的基于三角形的抗势力磁铁显示出具有平面内部旋转方向的非平地依赖性。旋转从相反的意义上的旋转到非常低场的场演变为与某些临界场尺度上方相同的磁场旋转。在后一个典型中，系统将显示旋转角度跳跃的一阶转换，而这些一阶线在Ising通用类别的关键点中终止。讨论了对MN $ _3 $ SN的申请。
We show that triangle-based antiferromagnets with "anti-chiral" order display a non-trivial dependence of the spin orientation with an in-plane field. The spins evolve from rotating in the opposite sense to the field at very low fields to rotating in the same sense as the field above some critical field scale. In the latter regime the system displays first order transitions at which the spin angles jump, and these first order lines terminate in critical points in the Ising universality class. Application to Mn$_3$Sn is discussed.
