Single-Spin Magnetic Resonance Force Microscopy

摘要

IBM and its subcontractors achieved the major goal of this contract: the detection of individual electron spins by magnetic resonance force microscopy (MRFM). To achieve this result a number of key elements were developed, including a low temperature apparatus capable of detecting ultrasmall (attonewton) forces, specialized cantilever force sensors, methods for manipulating and detecting electron spins with random initial polarization, etc. In addition, both theoretical and experimental work has been performed to study MRFM detection of nuclear spins.
