Doping effect of Mn2+ on the magnetic behavior in Ni–Zn ferrite nanoparticles prepared by sol–gel auto-combustion

Influence of Zn substitution on the structural and magnetic properties of Co1-xZnxFe2O4 nano-ferrites

“…As Zn 2+ concentration increases, the iron ions left at A-site, being small in number, the A-B interaction experienced by B-site iron ions decreases. Also, the increased number of Fe 3+ ions at the B-site increases the B-B interaction, resulting in spin canting [24]. The low values of M r /M s ratio indicate an appreciable fraction of supermagnetic particles.…”

Role of Cr3+ ions on the microstructure development, and magnetic phase evolution of Ni0.7Zn0.3Fe2O4 ferrite nanoparticles

“…The mean ionic radius of the A-and B-sites (r A and r B ) can be calculated using the relations discussed elsewhere [28,29]. The variation of r A and r B is shown in Fig.…”

Structural and Magnetic Properties of Mn<sub>0.50-x</sub>Zn<sub>0.50</sub>Cu<sub>x</sub>Fe<sub>2</sub>O<sub>4</sub>

“…It is well known that Zn 2+ ion has strong A-site occupancy, Mn 2+ ions prefer to go both sites (80% A-and 20% B-sites) [16]. Also Cu 2+ and Fe …”
