Abstract

Well-oriented permanent magnets of CoPtW(P) alloys with the basal plane parallel to the surface and a columnar structure were obtained by electrodeposition. Relatively high saturation moments and coercivities, both in perpendicular and in parallel magnetic field, are obtained at thickness up to 20 μm. Temperature dependence was also investigated, showing a great decrease of the magnetic properties. Chemical post-treatments can strongly influence magnetic properties, decreasing saturation magnetisation and coercivity while increasing squareness ratio.
