The undercoolability of bulk samples of 
alloys is investigated
at four compositions (x= 18, 25, 30, 50) by application of the electromagnetic
levitation technique. Each alloy is undercooled approximately 100 times under
same experiment conditions. A model developed by Skripov is utilized to statistically
analyze the distribution of maximum undercoolings in order to gain insight
into the origin of nucleation. The results indicate that crystal nucleation
is influenced by the onset of magnetic ordering when the nucleation temperature
is approaching the Curie temperature.
