Effective synthesis of HgBa2Ca2CU308+y, the highest Tc superconductor

The preparation of the superconductor Hg‐1223 (see this month's title picture) with 60‐70% phase purity by a simplified route is reported. The material is produced in a single step from air‐stable mono‐oxides and exhibits a sharp superconducting transition, possibly due to the lack of observabl...

Zusammenfassung:The preparation of the superconductor Hg‐1223 (see this month's title picture) with 60‐70% phase purity by a simplified route is reported. The material is produced in a single step from air‐stable mono‐oxides and exhibits a sharp superconducting transition, possibly due to the lack of observable defects (see Fig.) .
