Research output: Contribution to journalConference articlepeer-review


A study was conducted to address the influence of domain wall pinning sites in the medium on the properties of the recorded track, in particular the output and signal/noise ratio. In the simulation, each cell was exchange coupled to its immediate neighbors. Exchange breaks between cells were introduced at random to act as domain wall pinning sites. The percentage of exchange breaks was varied from zero to 100%. Results from this study are discussed in detail.
