Nodal-to-nodeless superconducting order parameter in LaFeAs1−x P x O synthesized under high pressure

Superconductivity: Putting the pressure on iron-based superconductors Experiments show how iron-based superconductors synthesized under high pressure differ from those grown under ambient conditions. Iron-based superconductors are an exciting family of materials that exhibit unconventional supercond...
