Peculiar rodlike diffuse critical scattering above the type-I antiferromagnetic (AF/I) phase transition has been observed in the actinide compound UAs and demonstrates that the transition is in the vicinity of a Lifshitz point. A mean-field theory is proposed based on a anisotropic Hamiltonian and provides a reasonable description of the results.
