摘要
(Figure Presented) Single-chain magnets: A rational approach to decrease magnetic dipolar interactions led to the chain compound [Dy(hfac) 3{NIT(C6H4OPh)}] (see structure; NIT(R): 2-(4′-R)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide), the first rare-earth-radical-based single-chain magnet. The compound shows slow relaxation behavior, a dynamical crossover resulting from finite-size effects, and a very rich static magnetic behavior. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
