Understanding the decay of persistent current in superconducting rings remains obscure. Here, the authors show detailed agreement between measurements of the persistent current in isolated flux-biased rings and Ginzburg-Landau theory over a wide range of parameters, providing a quantitative picture of the free energy landscape.
