“…The E g mode is attributed to the symmetrical bending of oxygen with respect to Fe, while the T 2g mode is attributed to the asymmetric stretching of Fe. 18 In cubic spinel ferrites, activity patterns above 600 cm –1 are generally associated with the movement of oxygen in the tetrahedral group (A site), 19 and patterns below 600 cm –1 indicate characteristics of the ferrite octahedral group (B site). 20 , 21 In this study, the use of Mg ions instead of Ni ions had a minimal effect on the peak positions of the A 1g and E g modes, while a significant rightward shift for the T 2g mode reflects the characteristic change in the B site of ferrite.…”

Ferrite with high permeability, high magnetic loss, and a low Curie temperature is a highly promising material for hyperthermia applications in cancer treatment. In this work, Ni(0.29–x)Mg x Cu0.14Zn0.60Fe1.94O3.94 (NiMgCuZn) ferrites were prepared at different Mg ion concentrations. The dependence of the Mg ion contents on the crystal structure, magnetic, and permeability properties of NiMgCuZn ferrite was investigated. Structural characterization showed a high crystallinity of the materials and an increase in the lattice constant with the Mg ion content. The magnetic hysteresis loops revealed that the saturation magnetization decreased with an increasing Mg content. Furthermore, the permeability measurements showed an increase in permeability and magnetic loss with the doping of Mg. More importantly, the Curie temperature of the NiMgCuZn ferrite decreases with the Mg ion content and reaches 42.37 °C for x = 0.26 as well as a real permeability of ∼797.88@1 MHz and a magnetic loss of 0.316@1 MHz, which meet the requirements of tumor hyperthermia.

“…The band gap energy decreases from 2.579 to 2.103 eV for the samples which are sintered at 400 • C. The outcome shows that composition and annealing measure of the heat contained in the samples put a major impact on the optical characteristics [6][7][8].…”

“…These changes in magnetic ordering are owing to the cation's redistribution between tetrahedral and octahedral sites. Thus, the properties shown by ZnFe 2 O 4 ferrites are changed with the crystallite size and inversion of cations on the sites [8][9][10].…”

In this study, the influence of Tb 3+ substitution in zinc ferrite is reported. ZnTb x Fe (2−x) O 4 (x = 0, 0.025, 0.05, 0.075, 0.1, 0.125, and 0.15) were prepared using sol-gel auto-combustion technique. All the samples were sintered at 400 • C for 4 hours. The structure has been studied using XRD, FTIR, UV-visible, and VSM. X-ray diffraction evaluation demonstrates formation of spinel ferrite with nano size distribution. Vibrating sample magnetometer was used to study the magnetic properties of the samples. It was found that as terbium content increases, the coercive field decreases while the saturation magnetization increases. The Tb 3+ doped nanocrystalline zinc ferrites show ferrimagnetic behavior. FTIR analysis show the presence of two expected bands attributed to tetrahedral and octahedral metal oxygen vibrations at 320 and 450 cm −1 .
