自铁基化合物中发现高温超导电性以来,人们已经合成了众多具有不同间隔层的体系.同时科学家们为揭示铁基超导体高温超导电性的特征和起源,在实验和理论研究方面都投入了大量的精力.但是直到今天其高温超导电性的起源仍然没有得以解决,特别是对正常态性质背后的物理还存在很多争论.本文总结了铁基超导体系的晶体结构以及相图,并提供了一些指向具有更高转变温度T c的新超导体的提示和高温超导机理的线索. Since the discovery of high-temperature superconductivity in iron-based compounds, many systems with different spacer layers have been synthesized, and scientists have devoted their experiments and theoretical studies to reveal the characteristics and origins of high-temperature superconductivity of iron-based superconductors A lot of energy.But until now, the origin of high-temperature superconductivity still can not be solved, especially for the physics behind the normal state there are still many controversies.This paper summarizes the crystal structure and phase diagram of iron-based superconducting system and provides Some clues to the cues and high-temperature superconductivity mechanisms of new superconductors with higher transition temperature Tc.
