“…The initial permeability decreased, but the figure of merit for high-frequency applications, (μ i − 1) f r , and DC bias superposition characteristics ( Fig. 12) for NiCuZn ferrites can be effectively promoted by increasing Co 2 Y addition [24]. These results indicate that the development of the low-temperature sintering NiCuZn ferrites with superior DC superposition characteristics is an important research topic for power applications.…”

“…10). Recently, we investigated a minor amount of Co 2 Y ferrites addition effects on the microstructure, magnetic properties, and DC bias superposition characteristics of NiCuZn ferrites [24]. It was observed that Co 2 Y can effectively inhibit the grain growth due to Zener pinning effect (Fig.…”

Passive components have continuously improved in recent years in miniaturization, multi-functionality, performance, and energy efficiency. The requirements of portable devices, home appliances, automobiles, industrial equipment, and other products demand these improvements. The passive components used in these products have had to continuously become smaller and thinner to meet ever-higher performance requirements. During the last several years, the demand for power inductors with high-rated current has increased rapidly due to the diversification and reduction in operating voltage in portable electronic devices. The low-temperature firing NiCuZn ferrites and Fe-based alloy powders for inductors have attracted much attention in recent years, while the review of the materials and processes for multilayer power inductors has not been described in the open literature to our best knowledge. Therefore, this article is aimed to deliver an overview on the progress of the multilayer power inductors, from materials and processes' point of view.

“…In addition, closed pores in lower density samples disturb the movement of domain wall, so that the initial permeability decreases when closed pores exist. 14 Figure 8 also shows the typical relationship between permeability and DC-bias current, which indicates that the permeability will decrease with the increase of the DC-bias superposition magnetic field. The curves of all graded samples exhibited the same trend, which experiencing a plateau at the beginning, then decreasing swiftly and gradually declining at the end.…”

This work reports our recent studies on the microstructure and properties of NiCuZn ferrites, with particular interests in effects of solid-state reaction temperature on the sintering activation energy and DC-bias superposition characteristic. The theory of master sintering curve was used to investigate the densification evolutions of NiCuZn ferrites during sintering process. Experimental results demonstrated that materials with solid-state reaction temperature of 850°C exhibited the lowest value of activation energy, 577.6 kJ mol −1 . When the solid-state reaction temperature was lower than 800°C, reaction could not be perfectly completed, which would hinder the consolidation process during heating up. In addition, increased solid-state reaction temperature could facilitate the homogeneous grain growth, reduce the final grain size and improve DC-bias superposition characteristic. Possible mechanisms behind are discussed.
