Phys. Rev. Lett. 86, 4508–4511 (2001)Quantum-Mechanical Analysis of a Longitudinal Stern-Gerlach EffectReceived 28 August 2000; published in the issue dated 14 May 2001 We present the results of a rigorous quantum-mechanical calculation of the propagation of electrons through an inhomogeneous magnetic field with axial symmetry. A complete spin polarization of the beam is demonstrated assuming that a Landau eigenstate can be inserted into the field. This is in contrast with the semiclassical situation, where the spin splitting is blurred. © 2001 The American Physical Society URL:
