At low temperatures, this system is well described by a one-dimensional array of effective spin S=3 chains comprising the MnIII-NiII-MnIII trimers and treated as the S=3 Ising chain with the single-ion term (Blume-Capel model). Using the exact solution of the model and based on the picture that the random motion of the local domain walls dominates the low-temperature spin dynamics, we succeeded in reproducing the experimental results of the dc susceptibility X0, the ac susceptibility X, and the 19F-NMR relaxation rate T in a consistent manner.}, pages = {224419-1--224419-7}, title = {Spin correlation and relaxational dynamics in molecular-based single-chain magnets}, volume = {74}, year = {2006}, yomi = {キシネ, ジュンイチロウ and デグチ, ヒロユキ and ミトウ, マサキ} }
