Краткий обзор статьи: Non-equilibrium dynamics in a Ag(11%Mn) spin-glass has been studied by low frequency ac-susceptibility and magnetic relaxation experiments. The results unequivocally show that spin structures that memorize the cooling process are imprinted in the system. These imprinted structures disclose themselves through dramatic changes of the dynamics on re-heating the spin-glass through the temperatures where intermittent stops or changes of the cooling rate have been imposed. We can qualitatively interpret our results in terms of the droplet spin-glass model developed by Fisher and Huse [Phys. Rev. B 38 (1988) 373; 386].
