We have used ferromagnetic resonance spectroscopy to study the effect of the concentration of cobalt nanoparticles (5–9 nm) incorporated into ethyl methacrylate/acrylic acid copolymers (monomer ratios 100:1 and 10:1) on the magnitude of the resonant field in ferromagnetic resonance and on the effective magnetization of thin-film samples of these nanocomposite polymer materials. The cobalt nanoparticles were obtained by thermolysis of Co2(CO)8 in 5% solutions of the indicated copolymers in toluene. From the solutions obtained, we prepared films of thickness 1 μm on aluminum substrates.
