本文对渗流垂直介质(PPM)的磁性能、热磁稳定性和记录性能进行了系统的微磁学分析，PPM是一种由交换耦合的小尺寸磁性颗粒组成的具有密集分布的非磁性钉扎位的新型薄膜微结构。分析表明，与传统的颗粒垂直介质相比，PPM微结构可以显著降低介质噪声，同时保持足够的磁稳定性
In this paper, we present a systematic micromagnetic analysis on the magnetic properties, thermal magnetic stability, and recording performance of percolated perpendicular media (PPM), a novel film microstructure of exchange coupled small-size magnetic grains with densely distributed nonmagnetic pinning sites. The analysis shows that the PPM microstructure can substantially reduce medium noise over the conventional granular perpendicular media while maintaining sufficient magnetic stability
