N2 - A system presenting an antiferromagnetic (AF) phase of single-chain magnets (SCMs) is studied at low temperatures. The phase diagram is first discussed to specify the magnitude of the interchain couplings. Then, we show experimentally and theoretically that slow relaxation of the magnetization can still be observed in the AF phase, with a maximum of the relaxation time close to the AF-paramagnetic phase transition. This counterintuitive result shows that materials presenting such an ordered state can be used to design high temperature magnets using SCM-based materials.
