Title: Structure of Gd{sub 0.95}Bi{sub 0.05}Fe{sub 3}(BO{sub 3}){sub 4} single crystals at 293 and 90 K

Abstract

The structure of GdFe{sub 3}(BO{sub 3}){sub 4} single crystals has been studied by X-ray diffraction at 293 and 90 K. The crystals are grown from a flux in the Bi{sub 2}Mo{sub 3}O{sub 12}–B{sub 2}O{sub 3}–Li{sub 2}MoO{sub 4}–Gd{sub 2}O{sub 3}–Fe{sub 2}O{sub 3} system. The results of chemical analysis and structural study show that these crystals contain bismuth as an impurity. It is found that bismuth atoms are located at gadolinium sites in the structure. A decrease in the temperature is accompanied by a lowering of the symmetry from sp. gr. R32 (at 293 K) to sp. gr. P3{sub 1}21 (at 90 K). The presence of two types of iron chains with different geometries at 90 K promotes a change in the magnetic properties of these crystals with a decrease in the temperature.
