Open AccessSpin-flip-driven anomalous Hall effect and anisotropic magnetoresistance in a layered Ising antiferromagnet
The influence of magnetocrystalline anisotropy in antiferromagnets is evident in a spin flip or flop transition. Contrary to spin flops, a spin-flip transition has been scarcely presented due to its specific c...
