Abstract :
A systematic study of the Co1.4Ge0.4Fe1.2O4 system by X-ray, magnetization, and AC-susceptibility techniques is presented. The present system exhibits para-ferri-cluster spin glass transition for x⩽0.2, while x⩾0.3 it exhibits only a cluster spin glass transition. The AC susceptibility and DC magnetization data support the cluster spin glass ordering in the system. The system exhibits local spin canting behavior
