Low Temperature Magnetic Resonance Force Spectroscopy and Imaging

Magnetic Resonance Force Microscopy (MRFM) as first conceived by J. Sidles is a novel technique that can provide chemical specific three-dimensional images of a variety of complex systems with nanometer scale resolution. The majority of efforts in the field have been directed towards enhancing force sensitivity in order to achieve single electron spin detection. We have designed and build a temperature-compensated apparatus with enhanced cantilever displacement sensitivity to perform MRFM and are working towards a novel method of performing Magnetic Resonance Force Spectroscopy (MRFS). In this, the first of our two presentations we will describe the experimental apparatus for performing MRFS and imaging at 4K. In the second talk we will describe in more detail the methods we intend to use for performing spectroscopic studies.
