Summary: | Today's magnetic-field sensors
1
are not capable of making measurements with both high spatial resolution and good field sensitivity. For example, magnetic force microscopy
2
allows the investigation of magnetic structures with a spatial resolution in the nanometre range, but with low sensitivity, whereas SQUIDs
3
and atomic magnetometers
4
enable extremely sensitive magnetic-field measurements to be made, but at low resolution. Here we use one-dimensional Bose–Einstein condensates in a microscopic field-imaging technique that combines high spatial resolution (within 3 micrometres) with high field sensitivity (300 picotesla). |
