Fig. 4

a Quantitative analysis of different phases at top (fully consolidated), middle (partially consolidated) and bottom (loosely compacted region) of the consolidated material, (b) magnetization (M) vs magnetic Field (H) curves from top and middle regions, (c) second quadrant of the M-H curve of regions going from fully consolidated section of the material to less consolidated, (d) magnetic force microscope (MFM) image of the top region, (e) magnified view of the marked region in (d) which highlights the domain wall and presence of non-magnetic Sm2O3 phase and (f) Quantified phase shift degree based on the line indicated on (e). Values were measured based on the grey values and contrast of grains based on the MFM image. The different bands used in (f) (1-7) are just to highlight the change in magnetic moment from one domain to other.
