Possible superconductivity above 400 K in carbon-based multiwall nanotubes
arXiv:cond-mat/0111268
Abstract
Magnetization and resistance measurements were carried out on carbon-based multiwall nanotubes. Both magnetization and resistance data can be consistently explained in terms of bulk superconductivity above 400 K although we cannot completely rule out other possible explanations to the data.
