摘要：
The nature of the spin state below spin freezing temperature was studied in an icosahedral Tb-Mg-Zn quasicrystal by the thermoremanent d.c. magnetization (TRM) time-decay as a function of aging time and magnetic field. The system does not exhibit a highly degenerate free energy landscape with an ultrametric organization of metastable states, which makes it essentially different from canonical spin glasses, (C) 2002 Elsevier Science BY All rights reserved.
