Abstract : The great number of high performance magnetic core materials is surveyed and various direct current and alternating current characteristics of such materials are presented in table and chart formats. Figures of merit are derived and their suitability for a characterization of materials is discussed. These figures of merit are used to compare and evaluate such different types of core materials as laminated materials, powdered materials, and ferrites. Universal charts covering characteristics of high performance core materials over wide frequency and flux density ranges are presented herein. A portion of this report is devoted to the review and consolidation of various permeability concepts which are used to describe material characteristics at high frequencies.
