How to distinguish between Fe3O4 and g-Fe2O3?

Pure Fe3O4 is almost black in color and is significantly darker than g-Fe2O3, which has a slightly redish tint compared to Fe3O4. a-Fe2O3 is pretty much red in color, much more so than g-Fe2O3.

Anchoring Group Effects of Surface Ligands on …

The effect of the anchoring group of surface ligands on the magnetic properties, especially relaxometric properties, of PEGylated Fe 3 O 4 nanoparticles is investigated. Systematic experimental results together with in‐depth theoretical analysis reveal that the ligand binding affinity can largely vary the saturation magnetization, whereas conjugated anchoring groups can remarkably enhance ...
