Nanoscale Artificial Magnetic Structures.
Abstract
Over the past three years, we investigated patterned magnetic nanostructures and their applications in ultra-high density magnetic storage. We have (1) developed nanofabrication technology and fabricated various nanoscale and high density magnetic structures; (2) demonstrated advantages of patterned magnetic nanostructures, (such as self-formation of single domain, quantized magnetization, and control of switching field by controlling the size and shape of the structures); (3) proposed and demonstrated quantum magnetic disks--a new paradigm for magnetic storage (e.g. fabricated QMDs of 65 Gbits/in(2) density, which is nearly 100 times of the density in current commercial hard disks); and (4) developed micromagnetic modeling tool and used them to study the domain configurations and switching of patterned magnetic nanostructures, and to design and analyze nanoscale spin-valve memory elements. Our research has significantly advanced the development of future ultra-high density magnetic storage and sensors.
