Abstract

We report on structural and magnetic properties of Co-Cu-P granular layers, prepared by an inorganic sol-gel process. The structural properties were investigated using X-ray diffraction, infrared spectroscopy and scanning electron microscopy. Structural characterisation confirmed the polycrystalline nature of the layers. The compounds present in these layers are Na₃Co₉(PO₄)₇, NaNO₃ and NaCllts. At room temperature, the magnetic properties of the layers show an evolution of hysteresis loops with the concentration of copper.
