The modular approach is a powerful tool in current inorganic crystal chemistry. It enables not
only a more detailed analysis of the known structures and the determination of structural …

Since the discovery of iron-based superconductors, a new chapter has been opened in the
history of the development of high temperature superconductivity. In the past decade, there …

The discovery of iron-based superconductors (FeSCs), with the highest transition
temperature (T c) up to 55 K, has attracted worldwide research efforts over the past ten …

Atomic structure and electronic band structure are fundamental properties for understanding
the mechanism of superconductivity. Motivated by the discovery of pressure-induced high …

The neutron spin resonance is generally regarded as a key to understanding the
magnetically mediated Cooper pairing in unconventional superconductors. Here, we report …

Superconductivity is mutually exclusive with ferromagnetism, because the ferromagnetic
exchange field is often destructive to superconducting pairing correlation. Well-designed …

We have synthesized two iron fluo-arsenides $ A $ Ca $ _2 $ Fe $ _4 $ As $ _4 $ F $ _2 $
with $ A $= Rb and Cs, analogous to the newly discovered superconductor KCa $ _2 $ Fe …

We report the observation of discrete bound states with the energy levels deviating from the
widely believed ratio of 1∶ 3∶ 5 in the vortices of an iron-based superconductor KCa 2 Fe …

The recently discovered 12442-type ACa 2 Fe 4 As 4 F 2 (A= K, Rb, Cs) compounds are the
only iron-based superconductors (IBSs) with double FeAs layers between neighboring …

We report the transport and magnetic measurements on single crystals of CsCa 2 Fe 4 As 4
F 2, a recently discovered double-FeAs-layer superconductor with T c∼ 30 K. We observed …
