The overall results indicate that room temperature superconductivity appears to be reachable
The paper goes into more detail:
The
observed magnetic characteristics as a function of temperature, magnetic field and time,
provide evidence for weakly coupled grains through Josephson interaction, revealing the
existence of superconducting vortices. [0]
My layman interpretation is that they've observed a property of superconduction, however their graphite flakes didn't demonstrate any actual superconductivity.

- jpdoctor 14y ago1. 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
- jcfrei 14y agothanks for clearing that up for me!
