Abstract
From new magnetization measurements and our previous thermal analysis on th e first genuine organic ferromagnet, beta-phase para-nitrophenyl nitronyl n itroxide (T-c = 0.6 K), found in 1991, we have evaluated the variation of s ome dominant exchange interactions in this magnetic system in the course of a pressure-induced ferro- to antiferromagnetic transition (T-c = 0.45 K, P -c = 6.5 kbar).
