Abstract
The magnetic and conducting properties of freestanding Pt-Fe nanowires are investigated by means of molecular dynamics. Our investigation reveals the dependence between a wire’s conductivity and its geometry and magnetic properties. Ab initio calculations show there is no spin polarization of a current in stretched linear Pt-Fe nanowires with antiferromagnetic ordering. Spin polarization of electron transport is observed upon contraction of the wire and is accompanied by its transition into a zig-zag configuration.
