Pressure-induced ferro-antiferromagnetic transition in genuine organic compounds was observed for the first time in the β-phase p-NPNN crystal. This phenomenon is understood by the charge-transfer mechanism, in which some of the ferromagnetic exchange integral comes to compete with the antiferromagnetic one being enhanced via molecular orbitals under the hydrostatic pressure.
