Mixed cobalt-copper spinel ferrites Co x Cu 1Ψx Fe 2 O 4 with acicular shape, prepared from oxalate precursors at moderate temperatures, have been investigated by several techniques to relate the coercivity with structure. The cation distribution in these ferrites is sensitive to the thermal history
