In this dataset cycle we consider a multifactor nature of the self-organization procees of soft matter dissipative microstructures from the iron-containing colloidal precursors with different particle size under microwave irradiation. The resulting structures' morphology determined by the dehydration-aggregation procees under the microwave field, as well as their phase state, chemical composition and the degree of crystallinity, are shown to be dependent on the irradiation time, the microwave field power and the particle size of the chemical "precursor".
