SQUID measurements of susceptibility versus field H are fitted by =₀-₁H^a-1 at a given temperature T, for two classic spin-glasses: 4. 6% Mn in Cu (polycrystalline) and 37% Gd in Al (amorphous). ₁ (T) shows a much stronger anomaly than ₀ (T), while a (T) has a minimum at the freezing temperature T₅. The data can also be scaled according to ₀-=H^2{}f ( (T-{T₅) }{H^2{}}) with =51 and =4. 50. 5.
