Abstract
IN THIS PROJECT WE WILL EXPAND UPON THE EXISTING TECHNOLOGY OF MULTILAYER MAGNETIC THIN FILM COMPOSITES TO DEVELOP A PSEUDO-BULK MATERIAL WITH STABLE MAGNETIC PROPERTIES OVER THE ENTIRE 0 TO > 600 DEG C TEMPERATURE RANGE. THE SATURATION MAGNETIZATION AND PERMEABILITY OF THIS MATERIAL AT 600 DEG C SHOULD BE AT LEAST ONE ORDER OF MAGNITUDE BETTER THAN THE ROOM TEMPERATURE VALUES OF COMPETING FERRITES. THE TEMPERATURE STABILITY AND HIGH FREQUENCY RESPONSE OF THIS MATERIAL WILL ALSO BE MUCH BETTER THAN THAT OF LAMINATED METGLAS COMPOSITES. IN PHASE I, WE WILL PRODUCE LABORATORY SAMPLES OF THE VERY HIGH TEMPERATURE MATERIAL AND WE WILL DESIGN AND CONSTRUCT A MEASUREMENT SYSTEM TO DO RAPID, PRECISE, SEMI-AUTOMATIC CHARACTERIZATIONS OF THE CONSTITUTIVE PARAMETERS AS FUNCTIONS OF TEMPERATURE AND FREQUENCY BETWEEN 100 - 900 MHZ AND BETWEEN 20 - 600 DEG C.
