PROJECT TITLE :
Curie Temperature Distribution in FePt Granular Media
The Curie temperature distribution is a vital parameter affecting transition noise in heat-assisted magnetic recording. In this paper, we follow up on our recent report on a way to guage the Curie temperature distribution and offer modeling that validates the strategy furthermore provides the experimental bounds for its validity. Thermal modeling is used to determine whether or not the technique is sensitive to extrinsic sources of grain temperature variations, such as distributions in thermal boundary resistance. The technique is applied to a variety of FePt granular media films of varying alloy composition and chemical ordering, and we tend to notice the Curie temperature distribution to depend totally on grain ordering kinetics. We tend to conjointly gift results of grain switching probability as a operate of the applied magnetic field and notice a non-trivial dependence on the alloy magnetization.
