论文摘要
金属间的GD2PDSI3最近引起了很多兴奋，此前报告说，尽管具有中央质合性晶体结构，但它仍携带了手性磁性纳米 - 骨化。使用磁场依赖性的极化谐振弹性X射线散射（REX），我们发现的不是意外的不相互压力密度密度波（CDW）出现在订购过渡以下，波形与磁纹理相等。此外，我们在GD2PDSI3中显示了这些不一致的磁纹理是高度各向异性的，绝大多数自旋调制都位于六边形AB平面内。该观察结果与先前建议的非链球磁纹理和共面替代方案不兼容。因此，我们的结果驳斥了观察到的大型大厅的解释和GD2PDSI3中的NernST效应，因为拓扑磁性的磁性天空产生。
The intermetallic Gd2PdSi3 has recently generated a lot of excitement after reports that it hosts chiral magnetic nano-skyrmions despite its centrosymmetric crystal structure. Using magnetic-field-dependent polarized resonant elastic x-ray scattering (REXS), we find than an unexpected incommensurate charge density wave (CDW) appears below the ordering transition with a wavevector equal to that of the magnetic textures. Furthermore, we show these incommensurate magnetic textures in Gd2PdSi3 are highly anisotropic, with the vast majority of the spin modulation lying within the hexagonal ab-plane. This observation is not compatible with the previously suggested non-coplanar magnetic textures and coplanar alternatives are discussed. Our results thus refute the interpretation of the observed large anomalous Hall and Nernst effects in Gd2PdSi3 as arising from topologically-nontrivial magnetic skyrmions.
