概要

• 論文の詳細を見る

• Magnetic properties of a stable organic biradical, meta-phenylene bis(α-nitronyl nitroxide) (m-BNN), have been studied. The molecular ground state is found to be triplet (S=1) by the solution EPR measurements. An X-ray structure analysis reveals that m-BNN crystallizes in a dimeric fashion. Susceptibility of a m-BNN single crystal exhibits anomalous temperature dependence as a result of intermolecular exchange interactions. From an analysis based on the structure of magnetic energy spectrum, unusual gap formation in the m-BNN crystals is deduced. The origin of the gaps is discussed in the light of the peculiarity of Heisenberg integer spins.
