Аннотация: A theoretical investigation is performed of quantum coherent electron transport through a nano-structure that contains an impurity ion with an uncompensated magnetic moment. It is shown that the transmission coefficient of spin-polarized electrons has the Fano antiresonance. This effect appears as a result of exchange interaction bПоказать полностьюetween the spin of transmitted electron and the spin of impurity ion. It is shown that Fano antiresonance leads to a qualitative modification of the current-voltage characteristic of the structure responsible for the large value of magnetoresistance. © Allerton Press, Inc., 2012.
