A scanning quantum cryogenic atom microscope at 6 kelvin
Abstract/Contents
- Abstract
- The Scanning Quantum Cryogenic Atom Microscope (SQCRAMscope) is a quantum sensor capable of imaging electromagnetic fields emitted from a nearby sample. Here we streamline and improve the capabilities of the SQCRAMscope for studying quantum materials. We upgrade the cryogenics system by replacing the liquid cryostat with a closed-cycle system and adding a radiation shield. The minimum accessible sample temperature is thereby reduced to 5.7~K while maintaining suitably low sample vibrations. Sample loading and cold atom preparation are both additionally simplified. An improved sample mount allows more reliable and rapid exchange of samples, while simplified atom trapping requires less instrumentation without loss of trapping efficiency. One major application of the SQCRAMscope is imaging electric currents by measuring local variations in magnetic field. We discuss the theoretical grounding of this technique, as well as experimental preparation of samples for measurement. Data from iron-pnictide superconductors is used to demonstrate the technique.
