Open AccessA series of magnon crystals appearing under ultrahigh magnetic fields in a kagomé antiferromagnet
Geometrical frustration and a high magnetic field are two key factors for realizing unconventional quantum states in magnetic materials. Specifically, conventional magnetic order can potentially be destroyed b...

Open AccessMaximizing T c by tuning nematicity and magnetism in FeSe1−x S x superconductors
A fundamental issue concerning iron-based superconductivity is the roles of electronic nematicity and magnetism in realising high transition temperature (T c). To address this issue, FeSe ...

Open AccessTwo-magnon scattering in the 5d all-in-all-out pyrochlore magnet Cd2Os2O7
5d pyrochlore oxides with all-in-all-out magnetic order are prime candidates for realizing strongly correlated, topological phases of matter. Despite significant effort, a full understanding of all-in-all-out ma....

Absence of superconductivity in the doped antiferromagnetic spin-ladder compound (La,Sr)CuO2.5
A SPIN-½ Heisenberg antiferromagnetic ladder is a model system comprising parallel chains of interacting elemental spins. Spin ladders having an even number of chains have been predicted1á¤-6 to exhibit interesti...

Probable hole-doped superconductivity without apical oxygens in (Ca, Na)2CuO2CI2
THE presence of apical oxygens (above or below the CuO2 planes) has been regarded as indispensable for the occurrence of hole-doped superconductivity in the high-transition-temperature (high-Tc) copper oxide supe...

A new family of copper oxide superconductors Srn+1CunO2n+1+δ stabilized at high pressure
THE search for new copper oxide superconductors1 has been pursued mainly by exploring a range of chemical compositions (counter-cations and oxygen content) and reaction temperatures. We have explored the effects ...

Superconductivity at 110 K in the infinite-layer compound (Sr1-xCax)1-yCuO2
THE 'infinite-layer' parent structure1 of the copper oxide superconductors (Fig. 1) is the simplest structure containing the CuO2 sheets that are apparently essential to high-transition-temperature (high-Tc) supe...
