Abstract
We give a definite answer to the question whether or not the quasicrystal i- is a true three-dimensional spin glass by measuring the linear ( and ) and dc nonlinear susceptibilities [(T),. . .]. We show that the magnetic correlations expand over large distances with decreasing T and that (T) diverges following the spin-glass transition scaling law with finite . From and we deduce separately and in the H=0 field limit the number (1.3% of the Mn concentration) and the moment (large, 7.5) of the magnetic entities, which can be attributed to Mn clusters.
