Top: shift of the Pt (533) peak owing to thermal expansion. The solid curve shows the patterns collected during heating; dotted lines are used for the patterns collected during cooling. Bottom: platinum sample. Relative expansion of the lattice parameter. The slope k of the line Δa/a = k(T − Trt) are, respectively, (1.004 ± 0.004) × 10−5 (heating), (1.003 ± 0.004) × 10−5 (cooling) and (1.000 ± 0.008) × 10−5 (Kirby). |
