Figure 1
Neutron powder diffraction patterns of Fe3C at 100 K (ferromagnetic phase) and 600 K (paramagnetic phase). Experimental data are shown as points, the line giving the calculated pattern from the Rietveld refinement. The lower trace shows the difference between the observed and calculated values and the tick marks give the expected positions of the Bragg reflections. The 2θ values shown (168° and 90°) refer to the scattering angles of the HRPD detector banks. |
