Separating Real Superconductivity from Similar to Superconducting

Professor Michael Fuhrer of Monash University explains the challenges to definitively prove superconductivity. You'd think superconductivity would be easy to detect; it comes with zero electrical resistance, so if you measure resistance, and it's zero, you're done. Unfortunately there are many ways to get fooled. Generally you'll see multiple pieces of evidence for superconductivity in ...
