Effect of the δ-doping on the magnetoresistance effect in a magnetically modulated nanostructure

Abstract

With the help of the transfer-matrix method, we theoretically investigate the effect of the [Formula: see text]-doping on the magnetoresistance (MR) effect in a magnetic nanostructure, which can be realized by depositing two ferromagnetic strips on the top and bottom of a nanostructure and using the atomic layer doping technique. It is shown that an obvious MR effect can be obtained in this device, and it can be tuned by the position and weight of the [Formula: see text]-doping. This device can be used as a [Formula: see text]-doping-dependent MR device for magneto electronics applications.
