Future Work
- Extract the Ti
from the (100)
and (200) spectra and analyze it using extant XAFS analysis techniques.
- Measure the Ti spectrum in fluorescence using an energy discriminating
detector as an independent comparison to the DAFS measurement.
- Apply this technique to a material with more closely spaced
resonant energies for which energy discriminating detection would
fail. Gadolinium iron garnet is an excellent choice due to the
proximity of the Fe K and Gd LIII edges and to the
simplicity of its structure.
The DAFS technique presented in this
poster is a powerful addition to the XAFS tool box allowing
examination of materials with arbitrarily close resonant energies.
This is of particular value in the study of magnetic materials
composed of both transition metal and rare earth elements.
