New imaging reveals internal patchwork

Researchers applied scanning 3D X-ray diffraction to examine the bulk material. This method functions similarly to a medical CT scan but targets atomic arrangements inside crystals. The team discovered that the structure is not uniform as previously believed.

Study published in Physical Review Letters

The work involved collaboration with the European Synchrotron Radiation Facility located in France. High-temperature superconductivity remains a major discovery for electricity flow and powerful magnets. These findings impact research into future power grids and medical scanners.
