Abstract

The continuous variation of magnetic intermolecular interactions has been studied in the pressurized genuine organic ferromagnet, beta-phase para-nitrophenyl nitronyl nitroxide (T-c = 0.61 K), in which a pressure-induced ferro- to antiferromagnetic transition was observed under pressure around 6.5 kbar at 0.45 K. The rotation of the radical group C6H4NO2 around its symmetrical axis in crystallized molecules is pointed out to be essential to change magnitude and a sign of the dominant exchange interactions, rather than the shrinkage of the lattice parameters under pressure.
