摘要：

The Cu-Ni ferrite (Ni1-xCuxFe2O4) nanopowders were prepared using the sol-gel auto-combustion method. The synthesized nanopowder can be densified at a temperature lower than 950 degrees C. The Cu content has a significant influence on the electromagnetic properties, such as initial permeability, resistivity and dielectric loss tangent. The possible reasons that are responsible for the composition dependence of the main electromagnetic properties were discussed. (c) 2006 Elsevier B.V. All rights reserved.
