(a) FR220, (b) FR320, (c) SR240 and (d) AC240. The data are shown by the red circles, the refined model by the black line and the residual by the blue line. Weighted profile and Bragg factors, respectively Rwp and RBragg, are indicated for each diffraction pattern. Black arrows show the three main contributions of hematite, α-Fe2O3. Only frequencies of 3 and 15 data points were selected to draw the NPD and PXRD patterns, respectively.
