VERDUZCO, Jorge Alejandro et al. Magnetic Properties of Metal Polymer Composites for Ac Applications at High Frequencies. J. Mex. Chem. Soc [online]. 2016, vol.60, n.2, pp.58-61. ISSN 1870-249X.

This paper presents the soft magnetic properties of the Fe-, Ni-, Coand Fe-Co-Ni polymer composites. The composites were obtained with Fe, Ni and Co powders (99.9% purity) with particle sizes of 150, 10 and 2 mm, respectively. Ring-shaped samples were obtained using uniaxial compaction at 91 MPa. The Fe-Co-Ni-polymer composite has the highest value of the magnetic permeability (μ=54) at 107 Hz and saturation magnetization (Ms=10000 Am2Kg-1) higher than the Ni-polymer composite (4100 Am2Kg-1).
