摘要：

In type-I superconducting cylinders, bulk superconductivity is destroyed above the first critical current. Below the second critical current the "type-I mixed state" displays fluctuation superconductivity which contributes to the total current. A magnetic flux on the axis of the cylinder can change the second critical current by as much as 50 percent, so that half a flux quantum can switch the cylinder from normal conduction to superconductivity: the Aharonov-Bohm effect manifests itself in macroscopically large resistance changes of the cylinder.
