The spin‐dependent phase delay time of two‐dimensional electrons through a magnetic–electric barrier structure with/without an external electric field has been systematically investigated. The dependence of electron spin polarization on the applied bias, the incident wave vector, the incident electron energy and the height of the electric barrier has been addressed. It is found that the magnetic–electric barrier structure exhibits significant spin polarization under an external electric field, especially for electrons with small energies, where the spin polarization also displays a considerable wave vector‐dependent feature.
