Impurities and Inelastic Processes in Magnetic Tunnel Junctions
A. M. Bratkovsky, J. H. Nickel
We have studied tunnel magnetoresistance (TMR) in junctions with 3d ferromagnetic electrodes. Previously we predicted that defects in the barrier would result in reduced effective…
Spin Tunneling in Conducting Oxides
Alexander Bratkovsky
Direct tunneling in ferromagnetic junctions is compared with impurity-assisted, surface state assisted, and inelastic contributions to a tunneling magnetoresistance (TMR). Theoreti…
Step-induced unusual magnetic properties of ultrathin Co/Cu films: ab initio study
A. V. Smirnov, A. M. Bratkovsky
We have performed ab initio studies to elucidate the unusual magnetic behavior recently observed in epitaxial Co films upon absorption of submonolayers of Cu and other materials. W…
Non-collinear magnetism in Al-Mn topologically disordered systems
A. V. Smirnov, A. M. Bratkovsky
We have performed the first ab-initio calculations of a possible complex non-collinear magnetic structure in aluminium-rich Al-Mn liquids within the real-space tight-binding LMTO m…
