The effects of tetravalent and divalent substitution on the physical properties of Cu ferrites, prepared by a double sintering ceramic technique, have been investigated. It was found that substitution of Zn and Zr simultaneously enhanced sintering process and crystallization. The initial permeability drops sharply at certain temperature for stoichiometric composition, which makes Zn/Zr co-doped NiFe2O4 spinel ferrites a very promising candidate for magnetic switch, magnetic temperaturedoi:10.21608/ajnsa.2018.1933.1005 fatcat:elj6jkr5hrcobizk56nnlehr3a
