| Abstract Scope |
The emergence of wide band-gap semiconductors for high frequency power electronic applications has necessitated the need for development of compatible soft magnetic materials. Current state of the art soft magnetic materials beyond 100 kHz operating frequency range are Manganese Zinc and Nickel-Zinc ferrites. However, they suffer from lower saturation flux densities of 0.2-0.5 T thereby limiting the operating power. Soft magnetic composites have potential to overcome this limitation by incorporating a metallic phase with high flux density within a ferrite matrix with high resistivities. In this work, metal-ferrite nanocomposites are synthesized and characterized in terms of phase identity, microstructure, and figures of performance metrics. Phase identity and microstructural evolution will be characterized using XRD SEM and TEM. DC properties will be characterized via VSM using M-H loops and M-T curves. Permeabilities measured via impedance analyzer will also be correlated with microstructural changes. Core loss will be measured using two-winding techniques. |
