The time decay of the thermoremanent magnetization (TRM) has been measured in 1.0% Cu: Mn and 2.6% Ag: Mn spin-glasses. It is shown that TRM is neither an algebraic nor a logarithmic function of time, but it is found that TRM can be characterized by a "stretched" exponential: TRM=0exp[-C(t)1-n(1-n)]. Similar time dependences appear in the disorder-diffusion theory of Grassberger and Procaccia and the cooperative-relaxation theory of Ngai, but neither theory in its present form is directly applicable to spin-glasses.
