dc.description.abstract © Kazan Federal University (KFU)*. Resonant tunneling is studied theoretically for the asymmetric double-barrier antiferromagnetic tunnel junction (DAMTJ) with a bias voltage is applied. In this nanostructure, the direction of magnetization of the middle ferromagnetic layer is parallel (antiparallel) to the direction of magnetization of the top layer and antiparallel (parallel) to the direction of magnetization of the bottom ferromagnetic layer. Analytical expression for the transmission coefficient of the double-barrier nanostructure is received, which is expressed through single-barrier transmission coefficients taking into account the voltage drop on each barrier and spin degrees of freedom of the electron conductivity. The theoretical model of spin-polarized conductance and tunnel magnetoresistance in asymmetric DAMTJ in the quasi-classical approximation is developed. The dependences of the transmission coefficient and tunnel magnetoresistance on the applied voltage under resonant conditions are shown.
