摘要：

We argue that the conventional dynamic scaling expressions in spin glasses are relevant only above the temperature at which a maximum of the imaginary part of the ac magnetic susceptibility is observed. Then different methods to derive the critical exponent z-nu in Cd0.6Mn0.4Te independently from the spin-glass temperature give the same result z-nu almost-equal-to 10. We also discuss the values of the critical scaling exponents-beta and gamma.
