SQUID measurements of the time decay of the thermoremanent magnetization (field-cooled in 1000 Oe) at long time scale, 10^{2} < t < 10^{5} s, are presented for MBE grown Cd_{0.50}Mn_{0.50}Te. We found that for both thin (32 Å) and thick (2500 Å) layers the spin-glass dynamics is characterized by a similar value of k = -(1/T_{f})(dT_{f}/dlogt) > 0.05, indicating the absence of the phase transition at nonzero temperature under the experimental conditions.
