• Abstract: We have developed an inelastic wave scattering based colliding-probe bi-atomic magnetometer theory. We show a propagation growth blockade in single probe based magnetic field sensing schemes, revealing the root cause of strong suppression of nonlinear magneto-optical rotation effect (NMORE) in single probe based atomic magnetometers. We further show, both experimentally and theoretically, a colliding probe bi-atomic magnetometer that lifts this NMORE blockade. The directional energy circulation in this new atomic magnetometry technique results in more than two orders of magnitude increase in NMORE signal as well as greater than 6dB increase of magnetic field detection sensitivity. The new technique may have broad applications in photon gates and switching operations.

  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.

  A squeezed probe optical field can improve the sensitivity of the magnetic field measurements based on nonlinear magneto-optical rotation. An independent pump field, amplitude-modulated at the Larmor frequency of the bias magnetic field, allows us to extend the range of most sensitive NMOR measurements to sub-Gauss magnetic fields.

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

We show that the geometry of the ferromagnet plays also an important role, by setting the fundamental frequency of the magnonic resonator.
