Single Spin Magnetic Resonance Force Microscopy

Imaging using Magnetic Resonance Force Microscopy

We demonstrate one-dimensional nuclear magnetic resonance imaging of the semiconductor GaAs with 170 nanometer slice separation and resolve two regions of reduced nuclear spin polarization density separated by only 500 nanometers. This is achieved by force detection of the magnetic resonance, Magnetic Resonance Force Microscopy (MRFM), in combination with optical pumping to increase the nuclear...

Advances in Magnetic Resonance Force Microscopy

Over the years magnetic resonance techniques have demonstrated to be powerful structural characterization and diagnostic imaging tools that have had a profound impact in medicine, biology, chemistry, material science and physics. While NMR provides the ability to perform molecular structure determination by investigating the local surroundings of atoms and the binding characteristics of molecul...

Magnetic force microscopy using fabricated cobalt-coated carbon nanotubes probes

Magnetic force microscope ( MFM ) is a powerful technique for mapping the magnetic force gradient above the sample surface. Herein, single-wall carbon nanotubes (SWCNT) were used to fabricate MFM probe by dielectrophoresis method which is a reproducible and cost-effective technique. The effect of induced voltage on the deposition manner of carbon nanotubes (CNT) on the atomic force microscope (...

Magnetic Resonance Force Microscopy Cantilever Detection by Quantum Tunneling

Magnetic resonance force microscopy (MRFM) is a novel ultra-sensitive magnetic resonance detection scheme. In this scheme, forces are measured between a magnet-tipped cantilever and on-resonance spins. It has been proposed that this technique could be used to image biomolecules [1]. In order to increase the sensitivity of MRFM, it may become necessary to use radio-frequency (RF), rather than au...
