Spin injection in a single metallic nanoparticle: a step towards nanospintronics
arXiv:cond-mat/0601439 · doi:10.1063/1.2236293
Abstract
We have fabricated nanometer sized magnetic tunnel junctions using a new nanoindentation technique in order to study the transport properties of a single metallic nanoparticle. Coulomb blockade effects show clear evidence for single electron tunneling through a single 2.5 nm Au cluster. The observed magnetoresistance is the signature of spin conservation during the transport process through a non magnetic cluster.
