| description | The effects of Si+4 and Zn+2 substitutions on the structural and magnetic properties of Cu1−xZnx+ySiyFe2−2yO4 ferrites prepared by double sintering ceramic technique have been investigated. From X-ray diffraction analysis, it was found that substitution of Zn and Si enhanced sintering process and crystallization. The XRD peaks increase by increasing Zn and Si content. On the other hand, the initial permeability decreases sharply at Curie temperature for all samples, which makes Zn/Si co-doped CuFe2O4 spinel ferrites a very promising candidate for magnetic switches, magnetic temperature transducers (MTT), and for fabrication of temperature sensitive controller devices. The important change of Curie temperature of CuFe2O4 compound occurs by simply controlling the content of Zn and Si within CuFe2O4 and results in obtaining magnetic materials with desired Curie temperature. Magnetic hysteresis loop measurements show that the samples have soft magnetic character. |
