Abstract

An electron paramagnetic resonance (EPR) study of a single crystal of CoII-based single-chain magnets (SCM) is presented. Discrete resonant absorptions are associated to the presence of magnetic domains within the chains of finite lengths determined by a competition between intra-chain exchange interactions and thermally excited single spin fluctuations. The results are interpreted as a transition from single spin dynamics at high temperature (T ∼20 K), associated to the Kramers doublet ground state of the individual CoII ions, to archetypical SCM dynamics at low temperatures, where intra-chain correlations form long magnetic domains, whose average length is imposed by the concentration of defects in the sample. © 2013 Elsevier Ltd.
