Low-field-susceptibility and static magnetization measurements have been performed on the Co-Ga spin-glass. In the spin-glass state, the magnetic susceptibility at all measuring frequencies is independent of the magnetic defect concentration and smoothly approaches zero as T→0. This behavior is identified as an equilibrium property of the spin-glass state and is consistent with the work of Thouless, Anderson, and Palmer.
