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…

Magnetic and chemical properties of Cr-based films grown on GaAs(001)
D. H. Mosca, P. C. de Camargo, J. L. Guimaraes +5
We have investigated the magnetic and chemical properties of very thin Cr films, CrAs, and arsenized Cr grown by molecular beam epitaxy on Ga As (001), using x-ray photoemission sp…
