The time decay of the thermoremanent magnetization (ₓₑ₌) has been measured in 1. 0% Cu: Mn and 2. 6% Ag: Mn spin-glasses. It is shown that ₓₑ₌ is neither an algebraic nor a logarithmic function of time, but it is found that ₓₑ₌ can be characterized by a "stretched" exponential: ₓₑ₌=₀exp-C ({) ^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.
