ScienceScience DailyScientists discover a hidden flaw that challenges 40 years of superconductor science
Researchers have found that a copper-based superconductor studied for 40 years has a hidden patchwork crystal structure, overturning a long-held scientific assumption.
A superconducting material studied for 40 years has turned out to be far more complex than scientists believed. Advanced 3D imaging revealed a hidden patchwork of crystal structures, with unusually wide boundaries that may weaken superconductivity. The discovery challenges decades of scientific assumptions and could explain why some superconductors outperform others.
Scientists using advanced 3D X-ray imaging discovered that a well-studied superconducting material has a far more complex internal structure than assumed.
Instead of a uniform crystal, they found a patchwork of two slightly different atomic arrangements with boundaries hundreds of times wider than expected.
The findings, published in Physical Review Letters, challenge 40 years of superconductor theory and could affect research into future power grids and medical scanners.
The study found the material has unusually wide structural boundaries that may influence how electricity moves through it, which could reshape future work on power grids and medical scanners.
