The Qnami ProteusQ Scanning NV Microscope is a complete quantum microscope system. It is the first scanning NV (nitrogen-vacancy) microscope for the analysis of magnetic materials at the atomic scale. By combining NV magnetometry and scanning probe microscopy techniques into a single instrument, scanning NV magnetometry provides simultaneous acquisition of the sample’s topography and its surface magnetic fields with nanoscale resolution. 

Features

  • CW and pulsed Optically Detected Magnetic Resonance spectroscopy
  • High frequency pulsing capabilities
  • Measurement scripting abilities via Jupyter Notebook
  • Single electron spin sensitivity

Specifications

  • Sample size 12×12 mm
  • Scan range (80×80 um) 
  • Lateral spatial resolution: ~40 nm
  • Nominal magnetic field sensitivity: 3 μT/sqrt(Hz)
  • Operating Temperature: room T – 400 K at ambient. Low T capability at vacuum environment will be installed later
  • Microwave operating frequency bandwidth 2.5-3.5 GHz, 10Hz resolution
  • Ultra-low drift, closed-loop scanning

Applications

Good for magnetometry (magnetic nanostructures, spintronics, domain wall, magnetic textures, etc.), surface current mapping and thermometry (temperature imaging, thermal defects)
