Quadrupling the depairing current density in the iron-based superconductor SmFeAsO1–xHx

Nature Materials, Published online: 18 July 2024; doi:10.1038/s41563-024-01952-7

The authors report very high in-field critical current densities in Fe-based superconductors. They achieve this through doping to increase the carrier density and adding defects to pin vortices.Nature Materials, Published online: 18 July 2024; doi:10.1038/s41563-024-01952-7The authors report very high in-field critical current densities in Fe-based superconductors.
