Description
The magnetic structures in cubic RD2 (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 4a0/ √11 along [113]. This modulation is commensurate with the crystal lattice and leads to a nonprimitive cubic magnetic lattice with a translation of 4a0. The ionic magnetic moments are of a single magnitude, independent of position. The magnetic structure of ErD2 contains both a commensurate component that belongs to a cubic magnetic lattice with lattice parameter 4a0 and an additional incommensurate component. An intermediate magnetic structure of the type found in ErD2 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
