“…The resistivity can be increased by doping cations, which dissolve into the spinel structure and mainly occupy the octahedral sites, which led to the substitution of Fe 3+ ions. The substitution ions, such as Co 2+ , Mn 2+ and Ti 4+ ions, which do not participate in the electronic exchange dilute the Fe 2+ and Fe 3+ ion concentration on octahedral sites and also hinder electron hopping between Fe 2+ and Fe 3+ ions, which leads to the increase in resistivity [25,26].

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.
