Co-Zr-B alloys have been produced by melt-spinning followed by heat treatments. The magnetic properties of the Co-Zr-B melt-spun ribbons depend on the annealing temperature. The maximum energy product of the optimally annealed Co-Zr-B melt-spun ribbons (BH)[sub max]=4.74 MGOe, is comparable to those of the hard ferrites. The hard magnetic phase of the Co-Zr-B system alloys is found to be the metastable Co[sub 5]Zr phase.

    We have found that the addition of Cu to an FePt alloy film is an effective approach for reducing the ordering temperature of FePt. The coercivity of the FePtCu film is around 5 kOe after annealing at 300 °C, whereas that of FePt shows several hundred Oe. In the FePtCu film annealed at 700...
