We use chemistry to arrange unusual crystal structures that set up conflicting interactions between magnetic ions in the material. In these compounds i is not possible for a...

We propose to measure the powder-averaged spin excitation spectrum of LiFeAs, a new member of the ferropnictide family of superconductors. This compound is special because it is...

The iron-based superconductors (Fe-SC) are one of the most active and challenging topics in condensed matter physics. Very recently some of us (F. Bernardini et al.) have...
