High-Resolution Parallel-Beam Powder Diffraction Measurement of Sub-Surface Damage in Alumina-silicon carbide nanocomposite (2006)
Journal Article
Tanner, B., Wu, H., & Roberts, S. (2006). High-Resolution Parallel-Beam Powder Diffraction Measurement of Sub-Surface Damage in Alumina-silicon carbide nanocomposite. Advances in x-ray analysis, 49, 169-174

The sub-surface damage in ground and subsequently annealed alumina/silicon carbide nanocomposite has been studied by analysis of the x-ray diffraction line width as a function of incidence angle. Bragg peak broadening fell as the depth of penetration... Read More about High-Resolution Parallel-Beam Powder Diffraction Measurement of Sub-Surface Damage in Alumina-silicon carbide nanocomposite.

Synthesis of size controlled fcc and fct FePt nanoparticles (2006)
Journal Article
Nguyen, H., Howard, L., Stinton, G., Giblin, S., Tanner, B., Terry, I., …Evans, J. (2006). Synthesis of size controlled fcc and fct FePt nanoparticles. Chemistry of Materials, 18(26), 6414-6418. https://doi.org/10.1021/cm062127e

We report the synthesis of FePt magnetic nanoparticles using Na2Fe(CO)4 and Pt(acac)2 as reagents. This method allows good control over particle stoichiometry and ensures efficient mixing of Fe and Pt atoms in the alloy at the atomic scale. The use o...

Interface sharpening in CoFeB magnetic tunnel junctions (2006)
Journal Article
Pym, A., Lamperti, A., Tanner, B., Dimopoulos, T., Ruhrig, M., & Wecker, J. (2006). Interface sharpening in CoFeB magnetic tunnel junctions. Applied Physics Letters, 88(16), https://doi.org/10.1063/1.2195774

We report grazing incidence x-ray scattering evidence for sharpening of the interface between amorphous Co60Fe20B20 and AlOx during in situ annealing below the Co60Fe20B20 crystallization temperature. Enhancement of the interference fringe amplitude... Read More about Interface sharpening in CoFeB magnetic tunnel junctions.

A synthetic route to size-controlled fcc and fct FePt nanoparticles (2005)
Journal Article
Howard, L., Nguyen, H., Giblin, S., Tanner, B., Terry, I., Hughes, A., & Evans, J. (2005). A synthetic route to size-controlled fcc and fct FePt nanoparticles. Journal of the American Chemical Society, 127(29), 10140-10141. https://doi.org/10.1021/ja051669e

We report here a new synthetic route to FePt nanoparticles using a stoichiometric mixture of Na2Fe(CO)4 and Pt(acac)2. The structure of FePt nanoparticles, their size, chemical composition, and magnetic property can be controlled by various synthetic...

Direct evidence for compressive elastic strain at ground surfaces of nanocomposite ceramics (2005)
Journal Article
Tanner, B., Wu, H., & Roberts, S. (2005). Direct evidence for compressive elastic strain at ground surfaces of nanocomposite ceramics. Applied Physics Letters, 86(6), https://doi.org/10.1063/1.1862754

High-resolution grazing incidence x-ray powder diffraction has been used to provide direct evidence for the existence of a uniform compressive strain close to the surface of ground alumina/SiC nanocomposites. No such strain is found in ground surface... Read More about Direct evidence for compressive elastic strain at ground surfaces of nanocomposite ceramics.
