- 論文の詳細を見る
We have succeeded in synthesizing organic biradical crystals of m-Ph-V<inf>2</inf>[= 1,3-bis-(1,5-diphenylverdazyl-3-yl)benzene]. The intra and intermolecular interactions, which are deduced from the molecular packing in the crystal, are considered to form an alternating double chain. We evaluated the intramolecular ferromagnetic (FM) interaction from an analysis of the magnetic susceptibility of isolated m-Ph-V<inf>2</inf>molecules. We analyzed the magnetic susceptibility and magnetization curves of the crystals by the quantum Monte Carlo method and successfully explained these properties using an S = 1/2 FM alternating double chain model, which consists of antiferromagnetically coupled FM alternating chains. In addition, the magnetic susceptibility and specific heat showed anomalous behavior at T_{\text{N}} = 1.9 K, which indicates the magnetic phase transition to an antiferromagnetically ordered state.
