Fe xCo1-x alloy nanoparticles: Synthesis, structure, magnetic characterization and magnetorheological application

We present results concerning the synthesis of FexCo1-x (0 < x < 1) alloy nanoparticles (NPs) with different compositions by the chemical reduction technique and subsequent structural (XRD patterns), morphological (TEM images) and magnetic (VSM magnetometry) characterization. We have got excel...
