Abstract
We have applied a new method for analyzing the dynamical susceptibilit y to determine both the prefactor To for switching via thermal activat ion and the distribution of energy barriers of a 5% Co in silver film. The peak energy barrier was 185 K and In Gamma(0) was 31.5 +/- 0.5, c orresponding to a Gamma(0) ranging from 2.9 X 10(13) to 7.9 X 10(13) H z.
