摘要：

Oriented particulate Ba-ferrite (BF) media have been known to exhibit very narrow switching field distributions, due to a confluence of reasons based on the particle morphology and the direction of their magnetic anisotropy. In this study we report on extremely narrow switching fields observed in longitudinally oriented BF rigid disk coatings, which are primarily the result of strong positive magnetostatic interactions between adjacent platelets in the oriented assemblies. In the transverse direction, the interactions are negative, and the switching fields are large.
