摘要：
A systematic study of the Co1.4-xZnxGe0.4Fe1.2O4 system by X-ray, magnetization, and ac-susceptibility techniques is presented. From the present results it appears that this system orders into a custer spin glass state with the magnetic moment of the clusters randomly frozen, and it exhibits local spin canting behavior.
