Article Synopsis
- High pressure superconductivity in the iron-based superconductor FeSe(0.5)Te(0.5) was examined in experiments up to 15 GPa and 10 K using specialized equipment.
- Electrical resistance measurements revealed that superconductivity begins at 14 K under normal pressure and increases to 19 K at 3.6 GPa, but then decreases at higher pressures.
- The decline in superconductivity after 3.6 GPa is linked to structural disorder in the material, specifically changes in the Fe(SeTe)(4) tetrahedra observed in x-ray diffraction studies beyond 11 GPa.
