Dielectric breakdown in underoxidized magnetic tunnel junctions: Dependence on oxidation time and area
J. Ventura, R. Ferreira, J. B. Sousa +1
Magnetic tunnel junctions (MTJs) with partially oxidized 9 ÅAlO-barriers were recently shown to have the necessary characteristics to be used as magnetoresistive sensors in hig…
KrF pulsed laser deposition of chromium oxide thin films from Cr8O21 targets
N. Popovici, M. L. Parames, R. C. da Silva +4
Chromium oxides, CrxOy, are of great interest due to the wide variety of their technological applications. Among them, CrO2 has been extensively investigated in recent years becaus…
Morphological and Structural Characterization of Cro2/Cr2o3 Films Grown by Laser-CVD
P. M. Sousa, A. J. Silvestre, N. Popovici1 +1
This work reports on the synthesis of chromium (III, IV) oxides films by KrF laser-assisted CVD. Films were deposited onto sapphire substrates at room temperature by photodissociat…
Nanoscopic processes of Current Induced Switching in thin tunnel junctions
J. Ventura, J. P. Araujo, J. B. Sousa +3
In magnetic nanostructures one usually uses a magnetic field to commute between two resistance (R) states. A less common but technologically more interesting alternative to achieve…
