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 …

Superconductivity (SC) and ferromagnetism (FM) are normally antagonistic, and their
coexistence in a single crystalline material appears to be very rare. Over a decade ago, the …

Finding a new derivative structure of FeSe-based superconductors with a high
superconducting transition temperature (T c) is of great significance. Here, in this work, an …

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

The 12442-type Fe-based superconductor is the only system that possesses two FeAs
layers between neighboring insulating layers, which is worth the in-depth investigations. In …

Three new homoleptic six-coordinate Sm (III) complexes have been synthesized from β-
diketone ligand with different substituent groups. The structural characterization of these …

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 …

We report on the effects of 3.5 MeV proton irradiation in RbCa2Fe4As4F2, an iron-based
superconductor with unusual properties in between those of the pnictides and of the cuprate …

Recently, 12442 system of Fe-based superconductors has attracted considerable attention
owing to its unique double-FeAs-layer structure. A steep increase in the in-plane upper …

Here, by conducting a site-selective nuclear magnetic resonance (NMR) study on As 75, Cs
133, and F 19 nuclei, we reveal the characteristic dynamics of two-dimensional (2D) …
