Interface bonding of a ferromagnetic/semiconductor junction : a photoemission study of Fe/ZnSe(001)
M. Eddrief, M. Marangolo, V. H. Etgens +7
We have probed the interface of a ferromagnetic/semiconductor (FM/SC) heterojunction by a combined high resolution photoemission spectroscopy and x-ray photoelectron diffraction st…
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…
Immense tunnel magnetoresistance mediated by Coulomb blockade effect and current-driven magnetization reversal in Co clusters embedded in a TiO2 matrix
J. Varalda, D. H. Mosca, Y. -L. Zheng +6
This article was withdrawn by the authors due to misinterpretation of experimental data.
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…
Thermal enhancement of the antiferromagnetic exchange coupling between Fe epilayers separated by a crystalline ZnSe spacer
J. Varalda, J. Milano, A. J. A. de Oliveira +8
We have put into evidence the existence of an antiferromagnetic coupling between iron epilayers separated by a ZnSe crystalline semiconductor. The effect has been observed for ZnSe…
