论文摘要
基于铁的超导体对凝结物理学有重大影响。它们具有二维方形铁晶格的共同结构基序，并具有富有成果的物理特性作为强烈相关的电子系统。在广泛的研究中，准中铁基旋转液体化合物吸引了很多关注，作为研究磁和轨道排序之间相互作用的平台。在这些化合物中，发现BAFE2S3和BAFE2SE3在高压下表现出超导性，在低温下具有不同的晶体和磁性结构。我们报告了对BAFE2+D（S1-XSEX）3的基于铁的旋转液体化合物和最新研究的简要回顾。 BAFE2（S0.75 SE0.25）3位于两个不同磁相边界的附近，由于预计大磁波动对超导性的影响，进行高压实验以进行高压实验，这是预期的。还通过改变BAFE2+DSE3中的铁浓度来研究铁化学计量学对磁性和超导性之间相互作用的影响。
The iron-based superconductors had a significant impact on condensed matter physics. They have a common structural motif of a two-dimensional square iron lattice and exhibit fruitful physical properties as a strongly correlated electron system. During the extensive investigations, quasi-one-dimensional iron-based spin-ladder compounds attracted much attention as a platform for studying the interplay between magnetic and orbital ordering. In these compounds, BaFe2S3 and BaFe2Se3 were found to exhibit superconductivity under high pressure, having a different crystal and magnetic structure at low temperature. We report a brief review of the iron-based spin-ladder compound and recent studies for BaFe2+d(S1-xSex)3. BaFe2(S0.75 Se0.25)3 is in the vicinity of the boundary of two different magnetic phases and it is intriguing to perform high pressure experiments for studying superconductivity, since effects of large magnetic fluctuations on superconductivity are expected. The effect of iron stoichiometry on the interplay between magnetism and superconductivity is also studied by changing the iron concentration in BaFe2+dSe3.
