Novel Magnetic Devices
Abstract
This project was dedicated to the development of novel magnetic devices relevant to applications in the fields of sensors, storage, non-volatile, reprogrammable spin-based electronics. The devices envisioned in this project explored novel physical phenomena and new functionalities not yet explored. More specifically, devices the initial idea was to explore three types of phenomena will be explored: ballistic magnetoresistance, magnetic field proximity effect and spin drag. These three phenomena would then be exploited for the design of novel device architectures and to investigate the physical principles behind these devices. This project explored the design, preparation, measurement and theoretical study of these novel magnetic devices. Modern thin film techniques (sputtering and Molecular Beam Epitaxy) were used for the growth of the structures. These were combined with state-of-the-art photo and electron beam lithography to engineer the devices. Structural and chemical measurements at the nanoscale were used for characterization, and magnetotransport will be used to investigate their performance. Theoretical work input was used to design the most promising devices and to develop an understanding of the experimental results. More specifically the three general types of devices to be investigated have as key ingredients: Ballistic Magnetoresistance, Magnetic Field Proximity Effect, and Tunneling. These are novel devices that still require scientific basis to validate the science and to help further advances in technology.
