For optical pumping at normal incidence, this polarization may be enhanced significantly by resonant excitation at the quantum well ground state. Measurements in a side-pumping geometry, in which the ferromagnet can be saturated in very low magnetic fields, show hysteresis that is also consistent with spin-dependent transport.

Optical pumping - Wikipedia

Optical pumping is a process in which light is used to raise (or "pump") electrons from a lower energy level in an atom or molecule to a higher one. It is commonly used in laser construction, to pump the active laser medium so as to achieve population inversion.The technique was developed by 1966 Nobel Prize winner Alfred Kastler in the early 1950s.

Optical Pumping of Rubidium: Data and Conclusion

Optical Pumping of Rubidium Data Conclusion: One of the difficulties we encountered in our experiment was quantifying the uncertainty on the horizontal component of the magnetic field: the deviation on the measurements was on the order of 0.01%.
