Rabi oscillation of spin-polarized rubidium in the spin-exchange relaxation-free regime
The transient dynamics of atomic spins under oscillating and static magnetic fields have been studied in the spin-exchange relaxation-free (SERF) regime with a dual-beam configuration. The spin-relaxation rate can be accurately measured by detecting the transient response signal of the free induction decay (FID) process within several milliseconds ...

MEMS Non-Magnetic Electric Heating Chip for Spin-Exchange-Relaxation-Free (SERF) Magnetometer
The alkali metal atoms in spin-exchange-relaxation-free (SERF) atomic magnetometers require high temperature and non-magnetic environment. Increasing the temperature of the alkali metal atoms causes higher atomic density, which can enhance the intensity ...
