Spin filtering by ferromagnetic nanowires
A. T. Costa, R. B. Muniz
We show that electrical current flowing through nanowires made of ferromagnetic disordered alloys can become highly spin polarized.

Impurity Scattering Induced Entanglement of Ballistic Electrons
A. T. Costa, S. Bose
We show how entanglement between two conduction electrons is generated in the presence of a localized magnetic impurity embedded in an otherwise ballistic conductor of special geom…
