Abstract
- Co-substituted copper ferrites have been synthesized by a microwave-assisted hydrothermal method. X-ray diffraction confirms that Cu<subscript>1.0</subscript>Fe<subscript>2.0</subscript>O<subscript>4</subscript> presents both tetragonal and CuO monoclinic phases, whereas the Co-substituted copper ferrites are cubic single-phase structures. All materials were crystallized as ultrafine particles with very low sublattice distortions, and the lattice constants vary with the degree of substitution. Fourier-transform infrared and Raman spectroscopies suggest a short range of the crystal lattices. Magnetic analyses demonstrated that each of the ferrites exhibits soft magnetic behavior with low hysteresis loss and coercive force. Electrochemical impedance data indicate a strong relative permittivity and weak dielectric loss tangent to the Co-substituted samples. [ABSTRACT FROM AUTHOR]
