| 2 | Spectroscopic analysis and temperature-dependent dielectric properties of bulk Ni-Zn ceramics显示文摘In the present work,series of Zn ion-doped Ni_(1-x)Zn_(x)Fe_(2)O_(4)(0:0≤x≤0.5)ceramics were prepared by the double sintered solidstate reaction route to find out the influence of Zn2t ions on the crystal structure,lattice structure and dielectric behavior of parent NiFe_(2)O_(4).X-ray diffraction(XRD)study favors that all the prepared compounds belong to the cubic spinel structure.Lattice parameters found to have increasing value with increased Zn^(2+)ion substitution.The Raman scattering measurement discerns optical-active modes with blue shift as the doping increases.The dielectric constant(ε′)and dielectric tangent loss(tanδ)decrease with an increase in frequency and at higher frequency,both become constant.Dielectric parameters observe nonlinear behavior with increasing Zn^(2+)ion substitution.Room temperature dielectric constant of 10%Zn ion-doped NiFe_(2)O_(4)[Ni_(0.9)Zn_(0.1)Fe_(2)O_(4)]is much higher as compared to other prepared ceramics.The room temperature ac conductivity is found to increase with increase in frequency and temperature-dependent ac conductivity increases with increase in temperature. | Anand Yadav Pankaj Choudhary P.Saxena V.N.Rai A.Mishra | 2019 | Journal of Advanced Dielectrics2019，9，2： | 0 |
