Monitoring the magnetic properties of Cu2+ ion substituted tin ferrite synthesized from secondary resources

Sn1−xCuxFe2O4 nanoparticles (0 ≥ x ≤ 0.3) were successfully fabricated via a co-precipitation route at low temperature 80 °C for 1 h using low-cost secondary resources. Evidently, the results revealed that the Cu2+ ion content up to 0.1 was found to form tin ferrite and increasing of Cu2+ ion content up to 0.2 and 0.3 was seemed to obtain a secondary phase of copper ferrite nanorods. TEM images revealed that the produced tin ferrite powders were a high homogeneity cubic-like structure. Nevertheless, copper ferrite nanorods were confirmed. Meanwhile, magnetic properties of Sn1−xCuxFe2O4 nanoparticles relied on the copper ratio. Indeed, high magnetization (Ms = 56.5 emu/g) was fulfilled with copper content of 0.1 and it was decreased to (Ms = 40.2 emu/g) with increasing Cu2+ ion content to 0.3. Alternatively, the coercive force was found to decrease from 144.2 to 85.4 Oe with increasing the Cu ratio from 0.0 to 0.3.
