The magnetic structures in cubic RD/sub 2/ (R = Tb, Dy, Ho, and Er) have been studied with neutron diffraction. The dideuterides of Tb, Dy, and Ho have modulated magnetic structures with a periods of 4a/sub 0// ..sqrt..11 along (113). This modulation is commensurate with the crystal lattice and leads to a nonprimitive cubic magnetic lattice with a translation of 4a/sub 0/. The ionic magnetic moments are of a single magnitude, independent of position. The magnetic structure of ErD/sub 2/ contains both a commensurate component that belongs to a cubic magnetic lattice with lattice parameter 4a/sub 0/ and an additional incommensurate component. An intermediate magnetic structure of the type found in ErD/sub 2/ appears in the Tb, Dy, and Ho compounds above T/sub N/, but disappears below T/sub N/, giving way to the apparently more stable, commensurate structure mentioned above.
