Stochastic behavior of nucleationprocess during magnetization reversalon a nanoscale in a nanogranularCoCrPt alloy film is directly observedutilizing magnetic soft X-raytransmission microscopy, whichprovides a spatial resolution of 15 nm.Thermal fluctuations in the orientationof the magnetic moments of the grainsplay a dominant role for the stochasticnature of domain nucleation in this system.
