Abstract Mössbauer effect measurements have been performed on the quasi 1-d antiferromagnetic solid solutions of Rb2Mn1−xFexF5*H2O (x=0.50) as a function of temperature. Particular attention was paid to the region very close to the Neel point. The experimental spectra show definite relaxation effects which are attributed to short-range order with temperature dependent relaxation times. The solitor, model of non-linear excitations was applied. Experimental data on Fe(III) confirm the predicted exponential temperature dependence of the thermal excitation of moving domain walls.
