Abstract

A pressure-induced ferro- to antiferromagnetic transition in genuine organic compounds has been observed in the β-phase para-nitrophenyl nitronyl nitroxide crystal. The transition temperature (Formula presented) in the ferromagnetic state decreases as (Formula presented) for pressures (Formula presented) [(Formula presented)]. For (Formula presented) however, experiment demonstrates intrinsically the existence of an antiferromagnetic state as well as a pressure-induced enhancement of (Formula presented) with (Formula presented) The results are discussed within the context of theories derived from the unrestricted Hartree-Fock approximation.
