摘要：

A highly enhanced initial susceptibility is predicted theoretically for thin, amorphous ferromagnetic films when they are patterned as separate disks of appropriate dimensions. The relation between the required disk radius and the film thickness is given as a function of the exchange constant and the saturation magnetization of the amorphous material.
