• Abstract summary: We demonstrate electromagnetic induction imaging with an unshielded, portable radio-frequency atomic magnetometer scanning over the target object. The ability to scan the magnetometer over the object relies on the miniaturization of the sensor head and on the active compensation of the ambient magnetic field.

• Abstract: We demonstrate electromagnetic induction imaging with an unshielded, portable radio-frequency atomic magnetometer scanning over the target object. This configuration satisfies standard requirements in typical applications, from security screening to medical imaging. The ability to scan the magnetometer over the object relies on the miniaturization of the sensor head and on the active compensation of the ambient magnetic field. Additionally, a procedure is implemented to extract high-quality images from the recorded spatial dependent magnetic resonance. The procedure is shown to be effective in suppressing the detrimental effects of the spatial variation of the magnetic environment.

  Off-resonance artifacts in magnetic resonance imaging (MRI) are visual distortions that occur when the actual resonant frequencies of spins within the imaging volume differ from the expected frequencies used to encode spatial information. We propose to resolve these artifacts by lifting the 2D MRI reconstruction problem to 3D, introducing an additional "spectral" dimension to model this off-resonance.

  We develop an in-situ magnetic detection technique at megabar pressures with high sensitivity and sub-microscale spatial resolution. We observe the macroscopic magnetic transition of Fe3O4 in the megabar pressure range from strong ferromagnetism (alpha-Fe3O4) to weak ferromagnetism (beta-Fe3O4) and finally to non-magnetism (gamma-Fe3O4) The presented method can potentially investigate the spin-orbital coupling and magnetism-superconductivity competition in magnetic systems.

  cavity photons and ferromagnetic spins excitations can exchange information coherently in hybrid architectures.
