Tunnel magnetoresistance in Co nanoparticle/Co–C60 compound hybrid system

Year: 2006

Type: article

Abstract: A nanometer-scale hybrid film of Co particle/Co–C60 compound was prepared by alternate deposition of Co and C60 under UHV condition. All of Raman spectra, magnetization curves, and tunnel conductivity concluded that the hybrid system has a granular structure consisting of Co nanoparticles embedded in a Co–C60 compound matrix. The magnetoresistance ratio of 26% was obtained at 2K and 10kOe for the electron tunneling across the Co–C60 compound barrier. In addition, anomalously large bias voltage dependence was found in the magnetotransport properties.
