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

Kamihara and coworkers' report of superconductivity at T c= 26 K in fluorine-doped
LaFeAsO inspired a worldwide effort to understand the nature of the superconductivity in this …

The surprising discovery of superconductivity in layered iron-based materials, with transition
temperatures climbing as high as 55 K, has led to thousands of publications on this subject …

The response of the worldwide scientific community to the discovery in 2008 of
superconductivity at T c= 26 K in the Fe-based compound LaFeAsO1− x F x has been very …

We report the superconductivity at above 30 K in a FeSe-layer compound K 0.8 Fe 2 Se 2
(nominal composition) achieved by metal K intercalating in between FeSe layers. It is …

The simple binary compound SnSe has been reported as a robust thermoelectric material
for energy conversion by showing strong anharmonicity and multiple electronic valence …

Starting from a microscopic itinerant model, we derive and analyze the effective low-energy
model for collective magnetic excitations in the iron pnictides. We show that the stripe …

Silver niobate (AgNbO3) is considered as one of the most promising lead-free replacements
for lead-containing antiferroelectric (AFE) ceramics, and has been drawing progressively …

We have established a plot of the anion height dependence of superconducting transition
temperature T c for the typical Fe-based superconductors. The plot showed a symmetric …
