The chains exhibit ferromagnetic interaction between gamma-Fe2O3 nanoparticles that compose them as evidenced by an increase in blocking temperature from similar to 80 K in the case of isolated nanoparticles to similar to 120 K for chains.FUNCTIONAL FERROMAGNETIC COLLOIDSPROTECTED METAL NANOPARTICLESSCANNING-TUNNELING-MICROSCOPYGOLD NANOPARTICLESQUANTUM DOTSGAMMA-FE2O3 NANOPARTICLESSEMICONDUCTOR CLUSTERSCOBALT NANOPARTICLESCELLULAR-AUTOMATANANOCRYSTALStext::journal::journal article::research article
