In the work, a composite material, which is an iron coating on a copper microgrid with a mesh size of 50 μm, is investigated. Iron coatings were synthesized by electroless deposition using arabinogalactan as a reducing agent. Samples were investigated using transmission electron microscopy, Mossbauer spectroscopy and ferromagnetic resonance methods. Magnetic anisotropy in the grid plane was studied by measuring the FMR spectra. The results of the study are discussed by modeling the composite as a wireframe system of magnetic tubes.
