Spin-Polarized Tunneling as a probe of (Ga,Mn)As electronic properties
M. Elsen, H. Jaffres, R. Mattana +3
We present magnetic and tunnel transport properties of (Ga,Mn)As/(In,Ga)As/(Ga,Mn)As structure before and after adequate annealing procedure. The conjugate increase of magnetizatio…

Resonant tunneling magnetoresistance in epitaxial metal-semiconductor heterostructures
J. Varalda, A. J. A. de Oliveira, D. H. Mosca +4
We report on resonant tunneling magnetoresistance via localized states through a ZnSe semiconducting barrier which can reverse the sign of the effective spin polarization of tunnel…
