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.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
