摘要：
SQUID measurements of the time decay of the thermoremanent magnetization at long time scale, 10(2) < t < 10(5) s, are presented for MBE grown Cd0.50Mn0.50Te. We found that for both thin (32 Angstrom) and thick (2500 Angstrom) layers the dynamics is characterized by similar value of k = -(1/T-f)(dT(f)/dlogt) > 0.05, suggesting the absence of the phase transition at nonzero temperature.
