Carbon Magnets At Room Temperature

Bolie writes: "Trying to make high temperature super conductors yielded an unexpected result. The pure carbon bucky ball material was put under pressure to make sheets. That worked. Picture microscopic bubble pack. But the result was a sheet that was magnetic at room temperature. It has not escaped the attention of the discoverer, Tatiana Makarova, that this might be useful for a non-metallic computer memory. The material is also lighter than metals, flexible and transparent. Lasers anyone?"
