An unconventional approach to scaling based on the anomalous Hall effect is presented and utilized to demonstrate conclusively that epitaxial (metallic) Ga(0.98)Mn(0.02)As is a mean-field ferromagnet. Such a result provides strong support for the assertion that the underlying interactions can be treated within the framework of Landau mean-field theory, direct support for which had previously been lacking. This scaling approach also provides confirmation-albeit indirect-that the origin of the anomalous Hall effect in this system is intrinsic at the composition studied.
