Ferromagnetic Resonance Assisted Optomechanical Magnetometer

Pulsed Parametric Resonance Magnetometer

A finite-field optical magnetometer is demonstrated that suppresses spin-exchange collisions by dressing the atoms in a sequence of transverse AC-coupled 2π pulses. In the limit of short pulses, the attainable transverse polarization is unity. On resonance, the dressing field cancels the DC magnetic field, further suppressing spinexchange relaxation as compared to light-narrowed magnetometers. ...

Ferromagnetic resonance

Ferromagnetic Resonance

Ferromagnetism is used to characterize magnetic behavior of a material, such as the strong attraction to a permanent magnet. The origin of this strong magnetism is the presence of a spontaneous magnetization which is produced by a parallel alignment of spins. Instead of a parallel alignment of all the spins, there can be an anti-parallel alignment of unequal spins. This results in a spontaneous...
