论文摘要
我们描述了使用中子衍射的抗铁磁cumnas薄膜中Néel载体单轴磁各向异性和自旋流动旋转的测量。观察到磁场下磁性峰的抑制（100）峰的薄膜薄，表明它们经历了自旋拖动过渡。在同一层中自旋拖曳旋转的中子衍射和电子传输测量之间发现了良好的一致性，其形状相似，并且对获得的曲线的滞后作用，而中子测量值则可以定量确定整个抗fiferromagnet层的自旋触发范围。
We describe measurements of the uniaxial magnetic anisotropy and spin-flop rotation of the Néel vector in antiferromagnetic CuMnAs thin films using neutron diffraction. The suppression of the magnetic (100) peak under magnetic fields is observed for films as thin as 20 nm indicating that they undergo a spin-flop transition. Good agreement is found between neutron diffraction and electron transport measurements of the spin-flop rotation in the same layer, with a similar shape and hysteresis of the obtained curves, while the neutron measurements provide a quantitative determination of the spin flop extent throughout the antiferromagnet layer.
