Abstract

The critical exponent [Formula presented] for the random-field Ising model order parameter is determined using extinction-free magnetic x-ray scattering for [Formula presented] in magnetic fields of 10 and 11 T. The observed value is consistent with other experimental random-field critical exponents, but disagrees sharply with Monte Carlo and exact ground state calculations on finite-sized systems.
