Description:

A method for processing CoPt alloys with improved magnetic properties, which includes sealing a sample of a CoPt alloy in an evacuated quartz tube and heating the alloy to a high temperature to homogenize the alloy. The sample is then cooled at a controlled cooling rate, and then held at 600 degrees C. for hours to promote isothermal ordering, and finally the sample is quenched in mineral oil.
