Spin-lattice and conductivity relaxations are analyzed in the same frequency and temperature range in terms of the non-Arrhenius dependence of the correlation time. Both relaxations are then described using a single correlation function of the form f(t)=exp(-(t/τ)^(β)), with β=0.4 over the whole temperature range.engjournal articlehttp://dx.doi.org/10.1103/PhysRevB.56.5302http://journals.aps.org/open access537GlassesModelNMR.ElectricidadElectrónica (Física)2202.03 Electricidad
