通过透射 X 射线衍射研究了在 200 MPa 拉伸应力下退火的 Fe-Si-B-Nb-Cu 合金中磁各向异性的结构起源。法线矢量与拉伸方向（带方向）平行的（310）面的衍射峰出现的角度比垂直方向低约0.1°。这表明，垂直于拉伸方向的(310)面的间距比平行于拉伸方向的(310)面的间距大约0.2%。这是纳米晶软磁合金应力诱导磁各向异性结构起源的直接证据。
The structural origin of magnetic anisotropy in Fe–Si–B–Nb–Cu alloys annealed under a tensile stress of 200 MPa is studied by transmission x-ray diffraction. The diffraction peak of the (310) plane, whose normal vector is parallel to the tensile direction (ribbon direction), appears at a lower angle than the one perpendicular to it by about 0.1°. This indicates that the spacing of the (310) plane normal to the tensile direction is about 0.2% larger than the one parallel to it. This is direct evidence for the structural origin of the stress-induced magnetic anisotropy of nanocrystalline soft magnetic alloys.
