Pressure has long been recognized as a fundamental thermodynamic variable but its
application was previously limited by the available pressure vessels and probes. The …

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 …

Members of the CaK (Fe 1− x Cr x) 4 As 4 series have been synthesized by high-
temperature solution growth in single-crystalline form and characterized by x-ray diffraction …

The pressure dependence of the structural, magnetic, and superconducting transitions and
of the superconducting upper critical field were studied in sulfur-substituted Fe (Se 1− x S x) …

We report the temperature-pressure phase diagram of CaKFe 4 As 4 established using high-
pressure electrical resistivity, magnetization, and high-energy x-ray diffraction …

The iron-based superconductors A Fe 2 As 2 with A= K, Rb, Cs exhibit large Sommerfeld
coefficients approaching those of heavy-fermion systems. We have investigated the …

The pressure dependence of the upper critical field, H c 2, c, of single crystalline FeSe was
studied using measurements of the interplane resistivity, ρ c, in magnetic fields parallel to …

In order to study the effects of Mn substitution on the superconducting and magnetic ground
state of CaKFe 4 As 4 (T c= 35 K), members of the CaK (Fe 1− x Mn x) 4 As 4 series have …

Electronic nematicity is often found in unconventional superconductors, suggesting its
relevance for electronic pairing. In the strongly hole-doped iron-based superconductors, the …

We report the successful synthesis of FeSe 1− x S x single crystals with x ranging from 0 to 1
via a hydrothermal method. A complete phase diagram of FeSe 1− x S x has been obtained …
