Abstract
THIN FILM TYPE PERMANENT MAGNET MAY OFFER AN ATTRACTIVE ALTERNATIVE TO BULK MAGNETS FOR BIASING VARIOUS MICROWAVE DEVICES IN RADAR AND COMMUNICATION DEVICES. SPUTTERING HAS BEEN USED TO FABRICATE THIN FILMS (1-3 MICRONS) OF PERMANENT MAGNETS BASED ON SM-CO AND FE-ND-B ALLOYS HAVING HIGH ENERGY PRODUCTS AND HIGH COERCIVITIES, HOWEVER, FOR MSW DEVICES, SUFFICIENTLY THICK (100-150 MICRONS) PERMANENT MAGNET FILMS ARE NEEDED. THE PROPOSED PHASE I RESEARCH IS DIRECTED AT DEMONSTRATING A PRACTICAL, CONTROLLABLE METHOD OF FABRICATING HIGH QULITY THICK PERMANENT MAGNET FILMS. AN INNOVATIVE INTERFACE ENGINEERING APPROACH WILL BE ADOPTED TO BUILD A MULTILAYERED SPUTTERDEPOSITED FILM OF SUFFICIENT THICKNESS WHICH WILL ADHERE STRONGLY TO THE SUBSTRATE. THE GOAL IS TO PRODUCE PERMANENT MAGNET FILMS THAT EXHIBIT HIGH INTRINSIC COERCIVITIES AND LARGE REMANENT MOMENTS WITH STRONG MAGNETIC ANISOTROPIES.
