Superconducting Iron-Based Film (IMAGE) DOE/Brookhaven National Laboratory Caption An electron microscope image of one of the team's superconducting iron-based films is shown after the scientists irradiated the film with low-energy protons shows the resulting chains of defects (indicated by yellow arrows). The inset image shows a zoomed-in view of a typical defect chain.
