The ac susceptibility χac of the amorphous spin-glass-like Fe93Zr7 alloy was measured at low temperatures in a wide frequency range of 60 Hz to 100 MHz. The frequency dependence of the spin-glass temperature Tg can be well described by a Fulcher-type expression. It points to the non-equilibrium nature of the spin-glass transition in this alloy.
