Abstract

Electron tunneling through a one-dimensional double-barrier structure with ferromagnetic barriers and nonmagnetic external and central electrodes has been considered theoretically in the linear response regime. Magnetic moments of the barriers are assumed to be generally non-collinear, but oriented in a common plane. Transmission coefficients, tunnel conductance and tunnel magnetoresistance are calculated numerically as a function of the angle between barrier magnetizations.
