Competition between Thickness and Electrical Conditioning Influence in Enhancing Giant Magnetoresistance Ratio for NiCoFe/Alq3/NiCoFe Spin Valve

TL;DR

This paper investigates how spacer thickness and electrical conditioning compete to influence the GMR ratio in NiCoFe/Alq3/NiCoFe spin valves, proposing a model that integrates both factors validated by experimental data.

Contribution

It introduces an extended empirical model that accounts for both spacer thickness and electrical conditioning effects on GMR ratio in spin valves.

Findings

Experimental results validate the proposed model.

Spacer thickness and electrical conditioning can dominate GMR enhancement under different conditions.

The extended formulation successfully integrates both factors.

Abstract

Spacer thickness and electrical conditioning have their own influence in enhancing giant magnetoresistance (GMR) ratio. At some condition one factor can override the other as reported by experiment results. An empiric model about competition about these two factors is discussed in this work. Comparison from experiment results to validate the model are also shown and explained. A formulation is proposed to extend the existing one that now accommodates both spacer thickness and electrical conditioning in one form.
