Mnzn ferrites belong to the group of soft ferrite materials characterized by high magnetic permeability and low power loses. These materials are mainly used as cores for inductors, transformers, recording heads and noise filters among others. In this study, nanocrystalline MnZn ferrite with the chemical formula Mn1-xZnxFe2O4 with x=0.2, 0.4, 0.6, 0.8 has been successfully synthesized by glycine-nitrate auto-combustion process using glycine as a fuel and nitrates as oxidants. The structures and magnetic properties of the resulting powder were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and vibrating sample magnetometer (VSM). It is revealed from the XRD pattern than a significant amount nanocrystalline Mn1-xZnxFe2O4 ferrite with average crystallite size in the range 43.25-66.7 nm has been formed. The magnetic measurement gives a typical value of saturation magnetic of 34-69 emu/g and coercivity of 40-60 Oe.

MnZn Ferrite Characteristics

1. Outstanding low power loss in high frequency range (≥100kHz)

2. Outstanding saturation magnetic flux density from room temperature to high temperature (120°C).

3. Low relative loss factor and high impedance

4. High permeability

5. Stable permeability in wide temperature range (-20 ～ 100°C).

How to deal with the surface of ferrite magnet?

Ferrite magnets have good corrosion resistance, will not corrode when placed in water, can resist chemical attack by many alkaline solutions, dilute acids, organic solvents and some hydroxides, they are very suitable for salt water environments (no corrosion problems at all), Can be etched with acids such as hydrochloric acid and the surface is generally left untreated, ie does not require any protective coating.
