“…However, it was found that in nanoparticles the degree of inversion, i, increases with the decrease of nanoparticle size [23], with a corresponding enhancement of magnetic properties. Recently, it was reported that mixed zinc/calcium ferrites adopt an inverted spinel structure [24]. Thus, an inverted spinel structure is considered, in which the A 2+ ions in octahedral sites are 50% distributed between zinc and calcium: (Fe) Td (FeZn 0.5 Ca 0.5 ) Oh O 4 .…”

“…The saturation magnetization of zinc ferrite nanoparticles depends strongly on the preparation method, with a reported value of M s = 1.638 emu/g for ZnFe 2 O 4 prepared by microwave combustion method [33] and of M s = 13.11 emu/g for zinc ferrite obtained by sol-gel [24]. This is because zinc is a non-magnetic cation, its position in tetrahedral and octahedral lattice sites strongly influencing the maximum magnetization [33].…”

Magnetic nanoparticles of zinc/calcium ferrite and decorated with silver were prepared by coprecipitation method. The obtained nanoparticles were characterized by UV/Visible absorption, XRD, TEM and SQUID. The mixed zinc/calcium ferrites exhibit an optical band gap of 1.78 eV. HR-TEM imaging showed rectangular nanoplate shapes with sizes of 10 ± 3 nm and aspect ratio mainly between 1 and 1.5. Magnetic measurements indicated a superparamagnetic behavior. XRD diffractograms allowed a size estimation of 4 nm, which was associated with the nanoplate thickness. The silver-decorated zinc/calcium ferrite nanoparticles were successfully employed in the photodegradation of a model dye (Rhodamine B) and industrial textile dyes (CI Reactive Red 195, CI Reactive Blue 250 and CI Reactive Yellow 145). The nanosystems developed exhibited promising results for industrial application in effluent photoremediation using visible light, with the possibility of magnetic recovery.

“…There are reported studies about maghemite stabilized by calcium silicate, [71] magnesium, [72] silica, [73] dextran, starch, poly(ethylene glycol), polyethylenimine, poly(vinyl alcohol), poly(acrylamides), poly(lysine), and chitosan [60] in the literature. Another group of well‐known hyperthermic agents is based on ferrites, such as cobalt ferrite, [74] manganese ferrite, [74b,75] nickel ferrite, [74b] zinc ferrite [76] and some mixed ferrites like Co 1−x Mn x Fe 2 O 4 , [77] Ni 1‐x Zn x Fe 2 O 4 , [78] Zn 1−x Ca x Fe 2 O 4 , [79] Zn x Mn y Fe z O 4 and Zn x Co y Fe z O 4 [80] . Iron oxides are favored because of their biodegradable nature, biocompatibility, and superparamagnetic effects.…”

Hyperthermia generates heat as a cure for illness and it is not a chemical treatment. Nanomaterials are supposed to provide novel mechanisms to tackle photothermal and magnetothermal problems, with the potential also to deal with specific approaches to care. The present review outlines recent developments in the field of photothermal and magnetothermal responsive nanomaterials and the photothermal approach mechanism over the last years. These photo/magnetothermal nanomaterials are classified into gold nanostructures (various shapes), carbon nanomaterials (CNTs, fullerene, carbon quantum dots, and graphene), inorganic nanomaterials (Fe, Pt, Pd, Bi, MOF, MoSe2, inorganic quantum dots, etc.) and organic nanoparticles (PLGA (Poly Lactic‐co‐Glycolic Acid) and other nanopolymers). Different groups may be placed together to improve the potential of the photothermal/magnetothermal effects, treatments, drug delivery, and imaging. The review also describes synthesis strategies for photothermal/magnetothermal nanomaterials, physicochemical characterization, the role of size, size distribution, shape, and surface coating of nanomaterials, challenges, and future scopes of photothermal/magnetothermal responsive nanomaterials for therapy, controlled drug delivery, and imaging applications. The recent development in nanomaterial has shown great potential for tumor diagnostic and therapeutic applications in hyperthermia. Magnetic hyperthermia (also called thermal therapy or thermotherapy) is a type of cancer treatment in which body tissue is exposed to high temperatures (up to 41 °C) in presence of a magnetic field. Research has shown that high temperatures can damage and kill cancer cells, usually with minimal injury to normal tissues. By killing cancer cells and damaging proteins and structures within cells, hyperthermia can necrotize tumor cells. This treatment can be local, regional, or whole‐body hyperthermia, depending on the extent of the area being treated. Hyperthermia can be combined with anticancer drugs or chemotherapy to enhance cancer treatment. In this article, we have discussed recent nanomaterials utilized for this treatment, mechanism, and synthesis methods.

“…Furthermore, advantages of soft ferrites include high resistivity, low cost, time and temperature stability, low loss and high permeability [43][44][45][46]. Most common soft ferrites are MnZn ferrites [47][48][49][50][51][52][53][54][55] and NiZn ferrites [56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71][72][73]. MnZn ferrites are more preferred as they have high permeability [74] and saturation magnetization [75]as compared to NiZn ferrites.…”

Researchers are taking great interest in the synthesis and characterization of MnZn ferrites due to their wide range of applications in many areas. MnZn ferrites are a class of soft magnetic materials that have very good electrical, magnetic and optical properties. The properties of MnZn ferrites include high value of resistivity, permeability, permittivity, saturation magnetization, low power losses and coercivity. The above mentioned advantageous features of MnZn ferrites make them suitable for the use in various applications. In biomedical field these ferrites are used for cancer treatment and MRI. MnZn ferrites are also used in electronic applications for making transformers, transducers and inductors. These ferrites are also used in magnetic fluids, sensors and biosensors. MnZn ferrite is highly useful material for several electrical and electronic applications. It finds applications in almost every household appliances like mobile charger, LED bulb, TV, refrigerator, juicer mixer, washing machine, iron, microwave oven, mobile, laptop, desktop, printer and so on. Therefore, the present review focuses on different techniques for synthesis of MnZn ferrites in literature, their characterization tools, effect of doping on the properties of MnZn ferrite and finally we will discuss about their applications.
