For high- or low-temperature single-crystal X-ray data collection, the glues used to bind crystals to silica rods may induce strong modifications of the intensities. When an yttrium iron garnet (YIG) crystal was cooled, reflections which were equivalent at room temperature became different. This is explained by strong stresses of the glue on the crystal which lead to an anisotropic modification of the secondary extinction. At low temperatures, `glues' such as beeswax or paraffin do not exert stresses.

Iron Garnet

The exsolution of magnetite from a substituted Yttrium Iron Garnet, containing an iron excess may lead to a transitional event. This event is characterized hy the formation of a transitional zone at the center of which the magnetite nucleates (Fig.1). Since there is a contrast between the matrix and these zones and since selected area diffraction does not show any difference between those zones and the matrix in the reciprocal lattice, it is of interest to analyze the structure of the transitional zones.By using simultaneously different techniques in electron microscopy, (oscillating crystal method microdiffraction and X-ray microanalysis)one may resolve the ionic process corresponding to the transitional event and image this event subsequently by high resolution technique.
