Scrutiny on the produced spin current in spin circuit considering Nano-magnetic nodes and copper Nano-channel

Abstract

Electronics of spin or spintronics is a newfangled field which its purpose is to study the role of electron's spin in solid-state devices. spintronic devices require spin current. Spin current is a difference between spin-up and spin-down electric currents. This article reviews the spin current. In this paper, we intend to calculate spin current in two spin circuits' branches. Also we investigate simultaneously effects of nano-channel length and cross section area variations on it.Our findings show that spin current in series branch increase by simultaneously length of nano-channel reduction and rising of cross section area. For spin flip branches, we can reduce dissipation by simultaneously length and cross section area nano-channel reduction. We choose copper metal as nano-channel because of longer spin diffusion length, less spin current dissipation and equality of its lattice constant with those of permalloy.
