ChemInform Abstract: Probing the Size Effect of Co2FeGa-SiO2@C Nanocomposite Particles Prepared by a Chemical Approach.

The title nanocomposite particles are prepared by addition of silica spheres to a dispersion of Fe(NO3)3, CoCl2, and Ga(NO3)3 in MeOH followed by sonication for 1 h and annealing at 850 °C for 5 h under flowing H2.
