چکیده
We have studied the influence of transverse size a magnetic tunnel nanojunction on magnitude magnetoresistance. During modeling, right contact was fixed, while left one gradually changed until they coincided. found sharp drop in tunneling magnetoresistance (TMR) nanocontacts with mismatched cross section. This can be explained by peculiarities spatial distribution electron density, which is different for majority and minority-spin states. The discovered effect must taken into account design TMR-based nanodevices.

Universal scaling of ballistic magnetoresistance in magnetic nanocontacts.
We show that ballistic magnetoresistance exhibits universal scaling in atomic or nanometer scale contacts. Plotting the data as conductance, we find that, if the maximum magnetoconductance is normalized to unity and the conductance is scaled with the conductivity of the bulk material, the data fall in a narrow region, independent of the nanocontact materials, for our four data sets and four fro...
متن کاملAnisotropic tunneling magnetoresistance and tunneling anisotropic magnetoresistance: Spin-orbit coupling in magnetic tunnel junctions
The effects of the spin-orbit coupling SOC on the tunneling magnetoresistance of ferromagnet/ semiconductor/normal-metal tunnel junctions are investigated. Analytical expressions for the tunneling anisotropic magnetoresistance TAMR are derived within an approximation in which the dependence of the magnetoresistance on the magnetization orientation in the ferromagnet originates from the interfer...
متن کاملMagnetoresistance of Half-Metallic Oxide Nanocontacts
Magnetoresistive effects R 0 -R H R H exceeding 500% are found at room temperature in a field of 7 mT in nanocontacts between Fe3O4 crystallites. The shape of the I V curve depends on field and the magnitude of the magnetoresistance is correlated with the resistance, the largest effects occurring when R . 100 kV. The explanation proposed involves hopping transport of spin-polarized electrons th...
متن کاملHeusler compounds with perpendicular magnetic anisotropy and large tunneling magnetoresistance
In the present work we suggest a recipe for finding tetragonal Heusler compounds with perpendicular magnetic anisotropy (PMA) that also exhibit large tunneling magnetoresistance (TMR) when used as electrodes in magnetic tunnel junction devices with suitable tunneling barrier materials. We performed density-functional theory calculations for 286 Heusler compounds and identified 116 stable tetrag...
