A MAGNETIC SUBSTANCE HAVING THE MAXIMUM VALUE OF COMPLEX PERMEABILITY IN QUASI-MICROWAVE RANGE IS PROVIDED FOR SUPPRESSING A HIGH FREQUENCY NOISE IN A SMALL-SIZED ELECTRONIC APPARATUS. THE MAGNETIC SUBSTANCE IS TO A MAGNETIC COMPOSITION COMPRISING M, X AND Y, WHERE M IS A METALIC MAGNETIC MATERIAL CONSISTING OF FE, CO, AND/OR NI, X BEING ELEMENT OTHER THAN M AND Y, BEING F, N,, AND/OR O.THE M-X-Y MAGNETIC COMPOSITION HAS A CONCETRATION OF M IN THE COMPOSITION SO THAT SAID M-X-Y MAGNETIC COMPOSITION HAS A SATURATION MAGNETIZATION OF 35-80% OF THAT OF THE METALIC BULK OF MAGNETIC MATERIAL COMPRISING M ALONE. THE MAGNETIC COMPOSITION HAS THE MAXIMUM MAX OF COMPLEX PERMEALIBITY IN A FREQUENCY RANGE OF 0.1-10 GIGAHERTZ (GHz).(FIG 1)
