Controlled atomic defects in nickelate films narrow down explanations of superconductivity emergence

An international team led by researchers at MPI-CPfS used irradiation with extremely high-energy electrons to controllably introduce atomic defects in superconducting nickelate thin films. Their systematic investigation recently published in Physical Review Letters helps to narrow down the possible answers to fundamental questions of how superconductivity emerges in these materials.
