Abstract
REQUIREMENT OF HEAVY AND VOLUMINOUS PERMANENT MAGNETS IN DEVICES SUCH AS MICROWAVE GENERATORS, NON-RECIPROCAL CIRCULATORS, ISOLATORS AND THEIR DEVICES MAKES THEM UNATTRACTIVE OF MANY SPACE AND WEIGHT RESTRICTED APPLICATIONS. INCORPORATION OF THESE DEVICES IN LARGE NUMBERS FOR ACTIVE APEMURE RADAR NECESSITATES THE DEVELOPMENT OF SMALL, MONOLITHIC CIRCULATORS BASED ON A THIN FILM MAGNET TECHNOLOGY. WE PROPOSE TO USE LASER ABLATION OF SPECIFIC METAL ALLOY TARGETS AS THE SOURCE OF REACTANTS FOR THE SYNTHESIS AND GROWTH OF THIN FILMS WITH THE PROPER MICROSTRUCTURE FOR ACHIEVING HIGH-ENERGY PRODUCTS AND COERCIVITY. THIN-FILMS OF RCOS AND PR2FEI7NX (X = 2 - 3) USING PULSED LASER DEPOSITION (PLD)IS DESCRIBED, HEREIN. EFFECTS OF WAVELENGTH AND PULSE DYNAMICS ON THIN-FILM MORPHOLOGY WILL BE INVESTIGATED. FILMS WILL SUBJECTED TO DETAILED MAGNETOMETRY FOR CHARADERIZATION. PHASE L WILL ALSO ENTAIL DESIGN OF A PLANAR NON- RECIPROCAL MICROWAVE DEVICE AND THIN-FILM PERMANENT MAGNET BIASING STRUDURE. THE ABILITY TO MANUFACTURE HIGH-ENERGY PRODUD THIN-FILM PERMANENT MAGNETS THAT HAVE GOOD
