The possibility of increasing diamagnetic susceptibility of pyrocarbon

A large increase of diamagnetism of pyrocarbon due to a decrease in concentration of the carriers and dependence of the magnetic susceptibility on the intensity of the magnetic field have been observed. The observed maximum diamagnetic susceptibility (—0.2% of —1/4 π) exceeds the values of all materials in the literature except superconductors.
