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…

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…
