Abstract
Bias dependence of the tunnel magnetoresistance in simple planar ferromagne tic junctions is considered theoretically within the one-band model. The li mit of sequential tunnelling in double junctions with a non-magnetic centra l electrode is studied as well. In this case tunnel magnetoresistance exist s only when the spin relaxation time due to spin-flip scattering processes inside the central electrode is sufficiently long.
