The Zeeman splitting of the conduction band in the magnetic semiconductor Cd1-xMnxTe with x<0.25 has been inferred from measurements of Fowler–Nordheim tunneling characteristics in a metal-semiconductor-metal structure. The large g value of the band electrons leads to a decrease of the barrier height in a magnetic field and, consequently, to an exponential increase in the tunneling current.

    We propose a spin selector based on periodic diluted-magnetic-semiconductor/ nonmagnetic-barrier (DMS/NB) superlattices subjected to an external magnetic field. We find that the periodic DMS/NB superlattices can achieve 100% spin filtering over a dramatically broader range of incident energies...

    We propose an optical switch based on a spin tuning mechanism in diluted-magnetic semiconductor quantum dots.
