Carbon in the News Again
Magnetic carbon 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. |
