Abstract
TbD2 and HoD2 have the calcium fluoride type of structure and become antiferromagnetic below 40° and 8°K, respectively. A powder neutron diffraction study of TbD2 at 4°K revealed a sinusoidal modulation of basic magnetic ordering of the first kind, in which ferromagnetic (001) layers are coupled antiparallel to the two adjacent layers. Both the magnetic moment and the wave vector are directed along the [001] axis, with a periodicity of about 24 Å. The moment associated with the Tb ion is 7.9 μB. The diffraction pattern observed for HoD2 was quite complicated and attempts to index the magnetic reflections either with multiple cell dimensions or with simple modulation of a few basic antiferromagnetic structures have proved unsuccessful.This publication has 4 references indexed in Scilit:
