“…The other broad band observed is due to Me T ─O─Me O stretching vibration at 600-500 cm À 1 , where O is oxygen, Me O is metal in the octahedral site and Me T is the metal at tetrahedral site. Normally these are the most prominent broad stretching vibrational bands observed in case of ferrite samples [12]. Bands observed beyond 900 cm À 1 are due to water molecules trapped inside the material.…”

“…By using this method we can synthesize MnZn ferrite at a very lower temperature. Tangsali et al [194] synthesized Mn x Zn 1-x Fe 2 O 4 (x=0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7) by using this method. All the metal salts were mixed in proper amounts in aqueous solution of dihydrazinium nitrilotriacetate.…”

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.

“…These powders on sintering produce bulk material with large porosity and nonuniform microstructure, which hampers the material performance. To overcome some of these discrepancies, bulk material can be prepared by sintering Mn-Zn nanoparticles, obtained by nitrilotriacetate precursor method [17] using modified microwaves based auto combustion technique.…”

The amazing magnetic properties exhibited by nanoparticles Mn-Zn ferrites and their promising technological and medical applications have attracted much interest in recent years. Nanoparticle Mn x Zn (1-x) Fe 2 O 4 spinel ferrites with x = 0.6/0.63/0.65/0.67/0.7 were synthesised by the nitrilotriacetate precursor method employing microwave combustion synthesis. Powder X-ray diffractometry (XRD) confirmed the formation of the ferrite phase in all samples. IR analysis was done to verify formation of spinel structure. Elemental analysis using EDS confirmed the nanoparticle composition. The crystallite size was calculated from peak widths using the Scherrer formula, yielding a size in the range of 10-25 nm. Transmission electron microscopy was also performed on the samples to testify formation of nanosized crystallites in the sample. Saturation magnetisation (Mr), retentivity (Ms) and coercivity (Hc) measurements were carried out on the samples using standard hysteresis High density nanoparticle Mn-Zn ferrite synthesis, characterisation 949 loop tracer equipment. The saturation magnetisation values were found to be in the range of 58.6-63.2 emu/g with very low values for (Mr/Ms). Variation of specific magnetisation with temperature and Curie temperature measurements were carried out using pulse field AC susceptibility measuring equipment. These measurements indicated formation of single domain (SD) material with dependence of Curie temperature on Zn concentration. The density of the samples was found to be high.
