Iron with a large magnetic moment was widely believed to be harmful to the emergence of
superconductivity because of the competition between the static ordering of electron spins …

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 …

Recently signatures of superconductivity were observed close to 80 K in La $ _ {3} $ Ni $ _
{2} $ O $ _ {7} $ under pressure [1]. This discovery positions La $ _ {3} $ Ni $ _ {2} $ O …

The dispersion of charge carriers in a metal is distinctly different from that of free electrons
owing to their interactions with the crystal lattice. These interactions may lead to …

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 …

This review shows the highlights of a 4-year-long research project supported by the
Japanese Government to explore new superconducting materials and relevant functional …

The focused ion beam (FIB) is a powerful tool for fabrication, modification, and
characterization of materials down to the nanoscale. Starting with the gallium FIB, which was …

In this review, the authors present a summary of experimental reports on newly discovered
iron-based superconductors as they were known at the end of 2008. At the same time, this …

Single crystalline samples of Ba (Fe 1− x Co x) 2 As 2 with x< 0.12 have been grown and
characterized via microscopic, thermodynamic, and transport measurements. With …
