Abstract

The previously accepted spatially modulated magnetic structure of CeAl 2 is shown to be incorrect. Neutron diffraction measurements in an applied magnetic field imply that the zero-field magnetic structure is spiral: however, the moments on the two Ce sublattices rotate in opposite senses. In the author's model, the magnitude of the Ce ordered moment varies little from site to site; a non-magnetic ground state for the Ce3+ ion is no longer required, and the extreme weakness of the harmonics is explained.
