چکیده انگلیسی
Dielectric properties of spinel ferrite samples Co1+xTixCr1.2−2xFe0.8O4 (0≤x≤0.5) were investigated as a function of frequency at different temperatures using a complex impedance technique. Also Cole–Cole diagrams of both permittivity and electric modulus were investigated at different temperatures to have an insight into the electric nature of the studied solids. It has been found that the electric modulus M* is the dominating property clarifying the intrinsic picture of these polycrystalline ferrites. The low conductivity and loss factor values indicate that the studied compositions may be good candidates for practical applications.
