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 …

Since the discovery of high T c iron-based superconductors in early 2008, more than 15,000
papers have been published as a result of intensive research. This paper describes the …

Understanding the competition between superconductivity and other ordered states (such as
antiferromagnetic or charge-density-wave (CDW) state) is a central issue in condensed …

Superconductivity in topological kagome metals has recently received great research
interests. Here, charge density wave (CDW) orders and the evolution of superconductivity …

Superconducting nickelates appear to be difficult to synthesize. Since the chemical
reduction of ABO 3 [rare earth (A), transition metal (B)] with CaH 2 may result in both ABO 2 …

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 …

Recently, Sukbae Lee et al. reported inspiring experimental findings on the atmospheric
superconductivity of a modified lead apatite crystal (LK-99) at room temperature …

Oxynitrides have been explored extensively in the past decade because of their interesting
properties, such as visible-light absorption, photocatalytic activity and high dielectric …

Fast ionic conductors have considerable potential to enable technological development for
energy storage and conversion. Hydride (H−) ions are a unique species because of their …

High-temperature superconductivity appears as a consequence of doping charge carriers
into an undoped parent compound exhibiting antiferromagnetic order; therefore, ground …
