p-nitrophenyl nitronyl nitroxide: the first organic ferromagnet

Witrynaan organic ferromagnet was one of the most conspicuous problems about 10 years ago. The first explicit theoretical approach for an organic ferromagnet was proposed as early as 1963 by McConnell (1963). However, no purely organic crystal was found to be a three-dimensional 'bulk' ferromagnet, even after extensive studies on the Witryna7 cze 1991 · Abstract.
