Abstract

A model example for size effects on the dynamic susceptibility behavior is provided by the chain compound [{Dy(hfac)3NitPhIm2}Dy(hfac)3] (NitPhIm = 2-[4-(1-imidazole)phenyl]nitronyl nitroxide radical). The Arrhenius plot reveals two relaxation regimes attributed to SMM (Δ = 17.1 K and τ0 = 17.5 × 10−6 s) and SCM (Δ = 82.7 K and τ0 = 8.8 × 10−8 s) behaviors. The ferromagnetic exchange among the spin carriers has been established for the corresponding Gd derivative.
