本文采用广义结构薄膜磁记录介质的动态微磁模型，研究了团簇尺寸对薄膜介质噪声的影响。模拟了由普通晶体学和晶间交换耦合形成的团簇，并给出了团簇对滞后和噪声的影响。对于一些晶粒的小集群，晶体学相关性被证明有相同的效果对噪声的晶间交换耦合，使磁特征尺寸和噪声的增加。>
A dynamic micromagnetic model of thin film magnetic recording media with generalised structure has been used to study the effect of cluster size on thin film media noise. Clusters formed by common crystallography and by intergranular exchange coupling have been simulated, and the effects of clustering on hysteresis and noise are presented. For small clusters of a few grains, crystallographic correlations are shown to have the same effect on noise as intergranular exchange coupling, giving an increase in magnetic feature size and noise. >
