NMR Spectrometers: Resolution and Error Correction

649
When magnetic nuclei in a sample achieve resonance and undergo relaxation, the signal detected in NMR is an approximately exponential free induction decay. Fourier transform of an exponential decay yields a Lorentzian peak in the frequency domain. Lorentzian peaks in an NMR spectrum are defined by their amplitude, full width at half maximum, and position, where the peak width is governed by the spin-spin relaxation time alone. In real experiments, however, the applied magnetic field is rendered...

Scanning Electron Microscopy

4.1K
A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

Area of Science:

  • Quantum sensing
  • Materials science
  • Nanotechnology

Background:

  • Scanning magnetometry using nitrogen-vacancy (NV) centers in diamond enables sensitive magnetic imaging.
  • Current spatial resolution is limited to tens to hundreds of nanometers, even with NV centers near the tip apex.

Purpose of the Study:

  • Investigate parameters limiting spatial resolution in NV-center magnetometry.
  • Improve magnetic imaging of sub-100-nm spin textures.

Main Methods:

  • Correlated investigation of mechanical/magnetic stand-off distances and NV center depth.
  • Utilized mechanical approach curves, photoluminescence, magnetometry scans, and NMR spectroscopy.
  • Employed frequency-modulated (FM) and amplitude-modulated (AM) atomic force microscopy (AFM) feedback.

Main Results:

  • Diamond tip surface features limit stand-off distance.
  • FM-AFM feedback achieves closer magnetic stand-off distances (26-87 nm) than AM-AFM (43-128 nm).
  • Demonstrated a minimum NV-to-sample distance of 7.9 ± 0.4 nm.

Conclusions:

  • FM-AFM enhances spatial resolution for NV-center magnetometry.
  • Improved technique enables imaging of nanoscale spin textures like spin cycloids and domain walls.
  • Optimized NV-to-sample distance is crucial for high-resolution magnetic imaging.
