Abstract

The statistics of nucleation are studied for different Co-Pd alloys by electromagnetic levitation. Each alloy was undercooled approximately 100 times under the same experimental conditions. A model developed by Skripov is employed to statistically analyze the distribution of maximum undercoolings in order to obtain information on the prevailing nucleation mechanism. The results of these investigations indicate that nucleation is influenced by magnetism when the nucleation temperature is approaching the Curie temperature.
