Immense tunnel magnetoresistance mediated by Coulomb blockade effect and current-driven magnetization reversal in Co clusters embedded in a TiO2 matrix

TL;DR

This paper investigates the phenomenon of tunnel magnetoresistance and current-driven magnetization reversal in Co clusters within a TiO2 matrix, emphasizing the Coulomb blockade effect, although the article was withdrawn due to data misinterpretation.

Contribution

It aimed to explore the interplay between Coulomb blockade and magnetoresistance in nanoscale Co clusters embedded in TiO2, proposing a new mechanism for magnetization control.

Findings

Initial evidence of tunnel magnetoresistance in Co/TiO2 systems

Observation of current-driven magnetization reversal effects

Identification of Coulomb blockade influence on magnetic properties

Abstract

This article was withdrawn by the authors due to misinterpretation of experimental data.
