  • The magnetic resonance imagers used in medicine fill rooms with their large-field magnets. But developments in ultra-low-field devices may give the doctor of tomorrow a more portable version.

  • The measurement of high magnetic fields has been limited to sensitivities in the nanotesla range. Here, the authors report advances in high-field magnetometry based on nuclear magnetic resonance, achieving resolution in the order of picoteslas or one part per trillion in relative terms.

  • Magnetic resonance imaging is widely used in the sciences and medicine, with the same basic underlying detection principle: the need for intimate coupling between nuclear magnetization in the sample under investigation and the detector. This study now shows a new detection principle, where the nuclear magnetization signal can be excited (and detected) via a long-range interaction utilizing travelling radiofrequency waves in a suitably modified MRI system. This approach offers more uniform coverage of larger samples.
