Abstract :
We studied a correlation between the local transition noise and the dc noise at the same location of magnetic medium. We describe experimental techniques for local dc noise and transition noise analysis and demonstrate that the local fluctuations of the dc saturated magnetization become enhanced when a transition is written at this location. This enhanced local dc noise is a very significant contributor to the total noise power of a transition.
