我们提出的结果共振x射线散射测量和电子结构计算的单砷化铁砷。我们阐明了磁结构的细节，表明自旋螺旋的椭圆率比以前认为的要大，为2.58（3），并揭示了自旋螺旋中磁矩的右手手性和面外分量。我们发现，电子结构计算和分析的自旋轨道相互作用能够定性地解释这种倾斜。
We present the results of resonant x-ray scattering measurements and electronic structure calculations on the monoarsenide FeAs. We elucidate details of the magnetic structure, showing the ratio of ellipticity of the spin helix is larger than previously thought, at 2.58(3), and reveal both a right-handed chirality and an out-of-plane component of the magnetic moments in the spin helix. We find that electronic structure calculations and analysis of the spin-orbit interaction are able to qualitatively account for this canting.
