Selected XRD scans of nanoparticles at selected temperatures. The vertical dotted line shows the shift of positions as the temperature is increased indicating lattice expansion.
Lattice parameters (a) -parameter (Å) and (b) -parameter (Å) for the hcp phase of plotted as a function of increasing temperature.
The thermal expansion coefficients (a) and (b) for and along those for bulk Ru and Co (shown as triangles from Refs. 12 and 13).
(a) Volume and (b) ratio as a function of temperature for .
