Abstract: C1.00126 : Spin transport and spin minibands in a magnetic superlattice: dependence on geometrical and physical parameters
Author:
We have studied the spin miniband structure and the ballistic spin-polarized
transport through a magnetic superlattice, formed by inhomogeneous magnetic
field in a semiconductor nanowire. Based on the transfer matrix theory and
the Bloch's theorem, we calculate the energy dispersion having spin miniband
and minigap due to Bloch periodicity and spin dependent ballistic
conductance for various geometrical and physical parameters. It is shown
that full spin polarization in the ballistic conductance of the system
occurs clearly for each spin, and that the fully spin polarized range for
each spin can be enhanced by modulation of geometrical and physical
parameters.
