The slow dynamics (10(-6) s-10(4) s) of the magnetization in the paramagnetic phase, predicted by Glauber for the 1d Ising model, has been observed with ac susceptibility and SQUID magnetometry measurements in a molecular chain comprising alternating Co2+ spins and organic radical spins strongly antiferromagnetically coupled to give a 1d ferrimagnet. An Arrhenius behavior with activation energy Delta = 152 K has been observed for ten decades of relaxation time and found to be consistent with the Glauber model. We have extended this model to take into account the ferrimagnetic nature of the chain as well as its helicoidal crystal structure.
