Abstract Scope |
Manganese Zinc Ferrites (MZF) offer low core loss at high frequency but are limited by a modest saturation flux density. This work explores a thermodynamically guided processing approach to enhance the saturation magnetization and magnetic performance of MZF using a controlled environment sintering that involves solid-state sintering of stoichiometric powder and a low-temperature H₂ reduction process. Thermo-Calc modelling is used to determine a processing window that selectively converts Feł⁺ to α-Fe by suppressing FeO and preserving the spinel framework. Structural and magnetic characterization, such as XRD, SEM, TEM, and VSM, was used to characterize the resulting composite microstructure and its properties. This study aims to establish a scalable route and promote a favorable microstructure for producing high-performance ferrite-based soft-magnetic nanocomposites with tailored magnetic properties. |
