1. Thanks for the arxiv link, (OP: it belongs at the top) 2. Magnetic characteristics of perfect diamagnetism are indeed "actual superconductivity." If there were some residual resistance, the magnetic field would not be completely expelled from that part of the material. Wikipedia's entry serves as a nice intro to diamagnetism, which is the underlying principle for the measurement. http://en.wikipedia.org/wiki/Diamagnetism http://en.wikipedia.org/wiki/Diamagnetism
