Chemists overturn 40-year assumption about a key class of superconductors

Chemists overturn 40-year assumption about a key class of superconductors

Scientists at Warwick have shown that a material treated for 40 years as a uniform, textbook superconductor is in fact a patchwork of different crystal structures throughout its bulk, using an advanced 3D imaging technique to see deep inside the crystal for the first time.
