Abstract
A method for processing CoPt alloys with improved magnetic properties. The method includes sealing a sample of a CoPt alloy in an evacuated quartz tube, and heating the alloy to a temperature of approximately 1000 degrees C. to homogenize the alloy for approximately 3 hours. The sample is then cooled at a controlled cooling rate of 120-150 degrees C. per minute to 600 degrees C. The sample is then held at 600 degrees C. for 10 hours to promote isothermal ordering. Finally, the sample is quenched in mineral oil.
