“…The spinel nanoferrites have not been studied intensively for magnetic hyperthermia. Therefore a few research studies include spinel nanoferrites [14][15][16][17][18]. The spinel nanoferrites are attracting materials.…”

Structural and magnetic properties of Mg x Zn 1−x Fe 2 O 4 powders have been studied with respect to the application for thermal cancer therapy (magnetic hyperthermia). Mg x Zn 1−x Fe 2 O 4 (x=0.1-0.5) powders with particle sizes between 5 and 8 nm were produced by citrate method. The X-ray diffraction patterns of the samples correspond to a spinel phase. The lattice constant and the volume of the elementary cell increase when x changes from 0.1 to 0.5. The FTIR-spectra ascertain the spinel phase formation. The Mossbauer studies reveal the presence of extremely small particles, which undergo superparamagnetic relaxation at room temperature. The core-shell model has been applied to explain quadruple doublets. The quadruple splitting at "shells" is bigger than those at "cores" whereas the isomer shifts remain close. Magnetic studies confirm the presence of extremely small particles that behave as superparamagnetic ones.

The effects of precipitation temperature on both structural and magnetic properties of polyethylene glycolcoated Mn 0.8 Zn 0.2 Fe 2 O 4 nanoparticles are presented. Samples were prepared via co-precipitation method at different precipitation temperatures ranged 25-100 • C. X-ray diffraction analysis revealed that both crystallite size and lattice constant of the nanoparticles increased with increasing of temperature. FESEM images verified the existence of crystalline ferrites of diameter ranged 7.49-9.41 nm. FTIR spectra evidenced the effect of precipitation temperature on Fe 3+ -O 2− stretching vibration in the ferrites. These Mn 0.8 Zn 0.2 Fe 2 O 4 nanoparticles exhibited the highest saturation magnetization 20.938 emu/g at 75 • C. Correlations among precipitation temperature alteration, structural morphology, and magnetic response are established.

“…51 MW syntheses may be used to synthesise metal oxides such as perovskites in solid-state reactions due to their inherent large dielectric constant and high dielectric loss. 52 This means they behave as a passive heating element when a MW field is applied. MW-assisted syntheses have been shown to be useful in producing materials which have a purer monocrystalline phase, in addition to allowing reasonable control over the crystallite growth and crystal structure depending on the reaction conditions.…”
