Resonant magnetic x-ray scattering measurements were performed on a single microcrystallite at the surface of a polycrystalline boule of the antiferromagnetic, heavy fermion superconductor UPd[sub 2]Al[sub 3]. These measurements show a strong anomaly in the order parameter at 11.8 K, below [ital T][sub [ital N]][similar to]14.5 K, indicating at least two antiferromagnetically ordered phases which share a common periodicity. Measurements performed at temperatures near and below [ital T][sub [ital c]]=2.0 K show the antiferromagnetic order parameter to be unaffected on passing into the superconducting phase, to [plus minus]2%.
