From new magnetization measurements and our previous thermal analysis on the first genuine organic ferromagnet, β-phase para-nitrophenyl nitronyl nitroxide (Tc = 0.6 K), found in 1991, we have evaluated the variation of some dominant exchange interactions in this magnetic system in the course of a pressure-induced ferro- to antiferromagnetic transition (Tc = 0.45 K, Pc = 6.5 kbar).
