Abstract
To account for the dependence of the crystal nucleation temperature in Co–Pd melts over the entire range from 50 to 100 at.% Co it is necessary to incorporate a contribution to the driving free energy that derives from the difference in magnetic free energies between liquid and melt. A simple molecular-field model provides a satisfactory fit of the earlier data.
