Consequences for Magnetic Properties of a Model to Explain Room-Temperature Superconductivity in Narrow Channels in Oxidized Polypropylene

There is published evidence suggesting that narrow channels through films of oxidized atactic polypropylene are superconducting at room temperature. Three properties combining to imply this are: (1) conductivity of channels at least several orders of magnitude higher than that of Cu at 300 K; (2) destruction of the high conductivity by nonthermal means when pulsed currents exceed a critical value; and (3) no observable electronic contribution to the thermal conductivity of the channels. Well-oxidized films also show unusual magnetic properties such as: (1) metamagnetism with transition fields in the range 0.1 to 0.2 T; (2) large diamagnetism at low fields in some films studied; and (3) occasional spontaneous forces tending to push samples toward lower fields in inhomogeneous magnetic fields. It will be shown that plausible explanations for these unusual magnetic properties can be found within the framework of a high-drift-velocity model introduced before to give a possible explanation for the electrical properties.
