The magnetic-resonance force microscope: a new tool for high-resolution, 3-D, subsurface scanned probe imaging

Magnetic resonance imaging of isolated single liposome by magnetic resonance force microscopy

“…In this paper, we rather concentrated on the application of MRFM for imaging a small sample with our available potentials, at room temperature with a commercially obtainable cantilever and a relatively larger magnetic tip. Imaging techniques and algorithms, such as well polished in MRI, are largely missing in MRFM [12,21,22], thus theoretical, experimental, and technological effort to improve the resolution and sensitivity is highly desired.…”

“…Magnetic resonance force microscopy (MRFM) [7][8][9][10][11][12], a promising MRI spectrometer combined with atomic force microscopy (AFM) technology, can provide the similar MRI experimental circumstance yet at much better spatial resolution. A few microns can be readily achieved [8,9,13,14] and the reported record was $20 nm [15] along a specific direction, the latter of which is almost by three orders of magnitude superior to the conventional MRI resolution.…”

Nuclear magnetic resonance imaging with 90-nm resolution

“…To quantitatively characterize the magnetic tips, we performed nanometer-scale magnetometry by measuring the MRFM signal as a function of tip-sample distance and applied magnetic field 15,20 . The sample was a 100 nm-thick film of CaF 2 (99.99%) evaporated onto the end of a mass-loaded silicon cantilever ( Fig.…”

Cooling a magnetic resonance force microscope via the dynamical back action of nuclear spins

“…Magnetic resonance force microscopy (MRFM) is a powerful technique for visualizing subsurface structures 1,2,3,4,5 with three dimensional spatial resolution of the order of 10 nanometers or less 6 , which is more than two orders of magnitude better than the resolution of conventional high-field magnetic resonance imaging (MRI). The main part of a MRFM device is a nanomechanical resonator or cantilever (see Fig.…”
