Number 43 (Story #1), August 1, 1991 by Phillip F. Schewe and Ben Stein AN ORGANIC FERROMAGNET , consisting only of light elements, has been discovered by scientists at the University of Tokyo. The new compound, p-nitrophenyl nitronyl nitroxide (abbreviated as p-NPNN, with a chemical composition of C13H16N3O4) possesses long-range ferromagnetic order below a transition temperature of 0.65 K. According to M. Takahashi et al., other claims of light-element organic ferromagnets concern materials with low magnetization or poor reproducibility. Like lightweight batteries, lightweight magnets would have numerous technological applications. (Upcoming article in Physical Review Letters.)
