The "giant" version of this effect has been observed in excitons in quantum wells.
The "giant" version of this effect has been observed in excitons in quantum wells. The Hamiltonian governing it is proportional to the orbital angular momentum plus twice the spin angular momentum, while Faraday rotation can be viewed as a consequence of this effect.  Its strength calculated with perturbation theory is proportional to the Bohr magneton and the Lande g-factor, while spin-orbit coupling breaks down in the presence of a strong field, which yields a variety of this phenomenon known as the Paschen-Back effect. For ten points, name this phenomenon first explained by a Dutch scientist that describes the splitting of energy levels in the presence of an external magnetic field.
