Abstract
Magnetic properties were studied between 300 K and 2 K. In antiferromagnetic UAs we observed very slow spin excitations. The spectrum in the type IA phase shows the presence of a tetragonal distortion. In CeAs the zero field data give TN = (7.6 ± 0.1) K. Just above TN short range order is present up to ca 8 K.
