论文摘要
我们报告了Fe $ _ {1-x} $ rh $ _ {x} $ ge化合物的全面实验和理论研究，在整个浓度范围内$ x \ in \ in \ weft [0.0-1.0 \右] $，使用X-ray衍射，小角度的中性散射，磁性和理论计算。虽然Fege和Rhge分别是单相的Helimagnet和非常规超导体，但对于中间组成$ X \ in \左[0.2-0.9 \ right] $，发现了晶体学和磁性状态的内部分裂。对两个检测到的阶段稳定性的理论分析以及实验数据表明，这种分裂保留了一个公共空间群，并发生在单一晶体内。尽管这两个阶段具有明显的相似性，但是具有不同的磁性结构，具有独特的铁磁特性。
We report on a comprehensive experimental and theoretical study of Fe$_{1-x}$Rh$_{x}$Ge compounds, within the entire concentration range $x \in \left[0.0 - 1.0\right]$, using X-Ray diffraction, small-angle neutron scattering, magnetometry and theoretical calculations. While FeGe and RhGe are single phase helimagnet and unconventional superconductor, respectively, an internal splitting of the crystallographic and magnetic states is found for intermediate compositions $x \in \left[0.2 - 0.9\right]$. A theoretical analysis of the stability of the two detected phases, together with the experimental data, indicate that this splitting preserves a common space group and occurs within single crystallites. Despite their apparent similarity, these two phases however display different magnetic structures, with distinct ferro- and helimagnetic character.
