Some aspects of the intrinsic magnetic behavior of metal particles for advanced recording media

The thermal stability and the magnetic anisotropy of advanced metal particles with high coercivity, useful in high performance recording technology, are investigated and compared with the behavior of previous generation metal particles. The results are discussed in relationship with the findings of the study of the magnetization switching. The role that the better morphological order of the advanced metal particles has in the determination of the basic magnetic behavior is underlined.
