Atomic-Scale Magnetic Devices
Abstract
As computing and memory devices approach the atomic scale, new methods, concepts, and device ideas are needed. Success in approaching the atomic scale will increase computational capability and reduce circuit volumes by increasing the packing density, an important direction for increasing DoD information processing capabilities. IBM proposes to perform exploratory research in measuring and controlling the magnetism of individual atoms, molecules, and precisely assembled nanostructures that are bound to a surface to study their basic physics and demonstrate concepts for future devices. The effort will make extensive use of atom manipulation, spin-polarized (SP) tunneling, and inelastic electron tunneling spectroscopy (IETS). Furthermore, it makes use of single-atom electron spin resonance (ESR), which provides extremely high energy resolution and coherent quantum control. The research explores magnetism at the atomic scale with emphasis on conductance through atoms and atomic wires, organic molecular magnetism, and the magnetism of individual lanthanide (rare-earth) atoms. This work is exploratory in nature so some goals may not be achieved in the proposal period while others may be exceeded. The goals of this proposal focus on the following four categories: (1) transport through atomic wires, (2) magnetism of organic radicals, (3) lanthanide atomic magnetism, and (4) electric-field control of charge and spin states.
