| Summary: |
We show switching probability measurements of individual bits of a bit patterned media in the highly inhomogeneous write field of a recording head. The behavior of the switching probability as a function of the applied field pulse width t deviates from a simple Arrhenius—Néel model for the magnetization reversal. The data agree well with an extended model that assumes a normal distribution of energy barriers. We compare the extracted energy barrier distribution to the switching field distribution in a uniform perpendicular magnetic field measured at long time scales.
