Abstract :
The permanent magnet properties of magnetic field aged Cr-Co-Fe alloys containing 5-9 weight percent (wt %) Co were investigated. By slow cooling from above the spinodal temperature under applied magnetic field, energy products of (BH)max= 4-6 MG . Oe were obtained. The effects of cobalt content, cooling rate, and applied magnetic field strength were studied.
