Open AccessUnusual competition of superconductivity and charge-density-wave state in a compressed topological kagome metal
Understanding the competition between superconductivity and other ordered states (such as antiferromagnetic or charge-density-wave (CDW) state) is a central issue in condensed matter physics. The recently disc...

Open AccessElectronic and magnetic phase diagram in KxFe2-ySe2 superconductors
The correlation and competition between antiferromagnetism and superconductivity are one of the most fundamental issues in high temperature superconductors. Superconductivity in high temperature cuprate superc...

Superconductivity at 5 K in alkali-metal-doped phenanthrene
Organic superconductors have π-molecular orbitals, from which electrons can become delocalized, giving rise to metallic conductivity due to orbital overlap between adjacent molecules. Here we report the discovery...

A large iron isotope effect in SmFeAsO1 - xF x and Ba1 - xK x Fe2As2
The recent discovery of superconductivity in iron-based oxypnictides with the critical transition temperature (TC) higher than 39 K has generated great excitement. Work to determine the origin of the superconduct...
