B. Bleaney et al., NEUTRON-DIFFRACTION STUDIES OF BALN(2)F(8) (LN=HO, ER AND TM), Journal of magnetism and magnetic materials, 144, 1995, pp. 1189-1190
The results of a neutron diffraction investigation on Ho, Er and Tm is
omorphs of BaLn(2)F(8) from 4.2 down to 0.3 K are described. A measure
ment on a powdered sample at 0.31 K was sufficient to determine the an
tiferromagnetic structure which has a (10 1/2) magnetic propagation ve
ctor for both the Ho and Er compounds.
