In the present paper the Co_{1-δ}Zn_{δ}Fe₂O₄ (0 ≤ δ ≤ 1) ferrite nanopowders with a spinel type structure were synthesized using a chemical co-precipitation technique with constant flow rate ν _{FR}=120 cm³/min at three different reaction temperatures i.e. T_r =50°C, 70°C and 90°C. Magnetic and structural characteristics of the obtained materials were investigated by means of X-ray diffraction method,...
The preparation of Ni_{0.2}Zn_{0.8}Fe₂O₄ nanofiber membranes by simple and versatile needleless electrospinning technique is presented. The single phase of spinel ferrite membrane was obtained after conventional thermal treatment of polyvinyl alcohol (PVA)/metal nitrate precursors at 800°C for 4 h in air. The formation of single-phase fibers was characterized using differential scanning calorimetry...
