Abstract
An in-plane spin-reorientation transition occurring during the growth of epitaxial Fe films on W(110) was studied in situ by using the nuclear resonant scattering of synchrotron radiation. The spin-reorientation transition originates at the Fe/W(110) interface and proceeds via a noncollinear spin structure resembling a planar domain wall that propagates towards the surface with increasing film thickness.
摘要
利用同步辐射的核共振散射，我们对在 W(110) 上外延生长的 Fe 薄膜的面内自旋重定向转变进行了原位研究。自旋重定向转变起源于 Fe/W(110) 界面，并通过类似于平面畴壁的非共线自旋结构进行，该结构随着薄膜厚度的增加向表面传播。
