The return from "quasi-two-dimensional'' to three-dimensional (3D) behavior of the spin-glass Ag0.91Mn0.09 is studied in multilayer samples of Ag-Mn layers of width 4 nm alternated with Cu interlayers of width 1 nm ≤ Wil ≤ 60 nm. For Wil (approximately-greater-than) 30 nm, the SG layers are magnetically decoupled; as Wil decreases below 30 nm, the quasistatic spin-freezing temperature Tf gradually rises toward the bulk spin-freezing temperature Tbf. When normalized to Tf/Tbf, the Ag-Mn data increase with decreasing Wil in a fashion similar to previous data for Cu-Mn. The data are compared with three different equations.
