TL;DR

This paper discusses how non-equilibrium spin currents can be generated and measured in two-terminal systems, demonstrating that spin currents can be produced in non-magnetic setups and detected using ferromagnetic probes.

Contribution

It introduces a method to generate and measure non-equilibrium spin currents in two-terminal non-magnetic systems using ferromagnetic detectors.

Findings

Spin currents can be generated in non-magnetic two-terminal systems.

Ferromagnetic probes enable measurement of these spin currents via conductance.

The approach provides a new way to study spin transport in simple device configurations.

Abstract

Generation and measurement of non-equilibrium spin current in two probe configuration is discussed. It is argued and shown that spin current can be generated in two terminal non-magnetic system. Further it is shown that these spin currents can be measured via conductance in two probe configuration when the detector probe is ferromagnetic.
