Orientation of Gd moments in RE/sub x/Gd/sub 1-x/Rh/sub 4/B/sub 4/ (RE = Ho, Er)
The orientation of the Gd magnetic moment with respect to the crystallographic axes in the magnetically ordered states of GdRh/sub 4/B/sub 4/ and RE/sub x/Gd/sub 1-x/Rh/sub 4/B/sub 4/ (RE = Ho and Er) materials has been studied with the /sup 155/Gd Moessbauer effect. Rare earth single ion anisotropies induced by the crystalline electric field (CEF) force the Gd moment to point in particular directions. These directions depend on which rare earth has been substituted into the lattice and will be discussed in terms of a CEF model for these materials. The results demonstrate that the /sup 155/Gd Moessbauer effect can be used as a probe of magnetic ordering directions in rare earth materials.
