Beschreibung:
<jats:p>Submicron particles of Fe–Co and Fe–Co–Ni alloys were prepared and stabilized with respect to air oxidation by surface polymerization. The addition of Co to Fe served to increase the saturation magnetic moment of polymer-coated Fe particles up to 50%. The coercivity also increased. Addition of small amounts of Ni to Fe–Co alloys decreased the coercivity. Aging tests were made to test the protection afforded by the surface polymer. The submicron alloy particles were found to be stable when heated at 97°C in air.</jats:p>
