  • Disorder emerges as a hidden tuning parameter in hole-doped iron-based superconductors, influencing phase transitions and magnetic properties. Here, the authors use neutron and x-ray diffraction to reveal a universal phase diagram, highlighting the role of atomic disorder in stabilizing magnetic phases and offering insights into the interplay of structural and magnetic parameters.

  • The Fe-based superconductors are an ideal family of materials to investigate the mechanisms of unconventional superconductivity due to the co-existence of both magnetic and superconducting phases. Here, the authors experimentally demonstrate the presence of three magnetic phases in LaFeAs1-xPxO, which can be tuned as a function of phosphorus content, and discuss how the results connect to wider trends in magnetic and superconducting orders of the Fe-based superconductors.
