Abstract :
This two-part tutorial article describes properties and applications of magnetically soft ferrites. These materials, which are characterized by high permeability and low losses, are used in very large quantities as cores for inductors and transformers. This first installment provides an elementary introduction to the processes of magnetization in ferrites. It also includes a survey of available grades and a summary of the technical properties of typical modern ferrites. Part II, to appear in February, reviews the main applications, describing how the material properties and performance requirements come together in the design of the device.
