Cover Story: The multiplicity of applications of soft ferrite cores in the realm of transfer, manipulation, and conversion of electrical energy is faced with a tradeoff between solid low-cost materials technology and components efficiency over a tremendous variety of working regimes and frequencies. We discuss the present state of knowledge on the magnetic losses of soft ferrites and their broadband behavior, by focusing on the physical mechanisms involved in the magnetization process, the displacements of the domain walls and the collective oscillation of the magnetic moments in the bulk. Eddy currents and damping of the motion of the precessing spins are the associated microscopic dissipation channels. With the theoretical background provided by the Maxwell and Landau–Lifshitz equations, their contributions are quantified through a generalized approach to the concept of loss decomposition. View this paper
