Description
Summary:Conventional longitudinal magnetic recording has scarcely progressed the last couple of years, leaving the data storage industry frantically searching for alternative ways to store information and increase memory areal density. The research was directed towards the development of three-dimensional magnetic memory for recording purposes. Three-dimensional memory, an alternative to longitudinal recording, would achieve well over the current areal density of the latter. Another focus of the research was directed towards development of the magneto-optical Kerr effect (MOKE) magnometer, an important tool used to measure magnetic behavior through hysteresis curves. The fabrication of three-dimensional media was prepared with the aid of a sputtering system and focused ion beam (FIB). Amongst the metals exploited for fabrication of three-dimensional media were cobalt, palladium, tantalum, and permalloy. Examination of fabricated magnetic films was investigated with utilization of the magneto-optical Kerr effect magnometer, atomic force microscope (AFM), magnetic force microscope (MFM), and x-ray diffractometer.
