Carbon in the News Again
has been reported by experimenter Tatiana Makarova, a Russian scientist
working in Sweden. The third form of carbon, buckyballs, the soccerball-shaped
structures containing 60 carbon atoms created in laboratories, exhibit
magnetic properties when compressed at a million lbs/in2
at a temperature of 1,300 ° F. Only iron, cobalt, nickel and gadolinium,
are naturally ferromagnetic at room temperature, which means they can
be permanently magnetized through exposure to a magnetic field. The
complicated proof of existence for these strange non-metallic magnets,
involving quantum mechanics, the Pauli exclusion principle and Heisenberg
theory, is left to the reader as an exercise.
