Abstract
To assess the effect of electronic structure of magnetic electrodes on the magnetoresistance of tunnel junctions (JMR) we made ab initio cal culations of the electronic structure of BCC(100) Fe, and FCC(100) Co and Ni electrodes. We treat hopping to and propagation in the barrier as adjustable parameters and discuss features of the JMR attributable to the electronic structure of the electrodes. (C) 1998 Elsevier Scien ce B.V.
