摘要：
Magnetization relaxation measurements show that aging occurs in a discontinuous metal-insulator multilayer (DMIM) [Co80Fe20(0.9 nm)/Al2O3(3 nm)](10) below the spin glass transition temperature, T-g approximate to 44 K. Furthermore, the DMIM system memorizes the structure of a quasi-equilibrium state reached after an intermittent stop-and-wait protocol during cooling. These results unambiguously corroborate the collective nature of the low temperature superspin dynamics. (C) 2004 Elsevier B.V. All rights reserved.
