Abstract
We theoretically investigate dwell time for electrons in a magnetic nanostructure with a [Formula: see text]-doping, which is formed on [Formula: see text] heterostructure by depositing a ferromagnetic (FM) stripe. We find that dwell time depends strongly on electron-spins owing to Zeeman coupling and broken symmetry. We also demonstrate that spin-polarized dwell time can be manipulated by [Formula: see text]-doping. Thus, electron spins can be separated in time dimension and such a magnetic nanostructure can be employed as a structurally-controllable temporal spin splitter for spintronics device applications.
